ガンマ線分光による$$N$$=40同調体である$$^{62}$$Tiの分光学研究を$$^{63}$$V($$p$$,$$2p$$)$$^{62}$$TiをRIBFで行った。今回初めて測定された$$2_1^+ rightarrow 0_{rm gs}^+$$$$4_1^+ rightarrow 2_1^+$$の遷移はTiの基底状態が変形していることを示唆した。これらのエネルギーは近傍核の$$^{64}$$Crや$$^{66}$$Feと比較して大きく、したがって四重極集団運動が小さくなっていることが示唆される。今回の結果は大規模殻模型計算によって良く再現される一方、第一原理計算や平均場模型では今回の結果は再現されなかった。

Fine structure in the $$alpha$$ decay of $$^{223}$$U was observed in the fusion-evaporation reaction $$^{187}$$Re($$^{40}$$Ar,p3n) by using fast digital pulse processing technique. Two $$alpha$$-decay branches of $$^{223}$$U feeding the ground state and 244 keV excited state of $$^{219}$$Th were identified by establishing the decay chain $$^{223}$$U$$rightarrow$$$$^{219}$$Th$$rightarrow$$$$^{215}$$Ra$$rightarrow$$$$^{211}$$Rn. The $$alpha$$-particle energy for the ground-state to ground-state transition of $$^{223}$$U was determined to be 8993(17) keV, 213 keV higher than the previous value, the half-life was updated to be 62$$^{+14}_{-10} mu$$s. Evolution of nuclear structure for $$N$$=131 even-$$Z$$ isotones from Po to U was discussed in the frameworks of nuclear mass and reduced $$alpha$$-decay width, a weakening octupole deformation in the ground state of $$^{223}$$U relative to its lighter isotones $$^{219}$$Ra and $$^{211}$$Th was suggested.

$$^{54}$$Caでは中性子魔法数34が現れると考えられているが、その直接的な実験的証拠を得るため、$$^{54}$$Caからの中性子ノックアウト反応$$^{54}$$Ca($$p,pn$$)$$^{53}$$Caによって生成される状態を理化学研究所のRI Beam Factoryによって調べた。基底状態および2.2MeVの励起状態が強く生成され、1.7MeVの励起状態の生成量は小さかった。$$^{53}$$Caの運動量分布から、基底状態および2.2MeVの励起状態は$$p$$軌道の中性子を叩き出して得られた状態であることが明らかになった。DWIA計算によって得られた分光学的因子から、$$^{54}$$Caは$$p$$軌道がほぼ完全に占有された閉殻構造を持つことが明らかになり、中性子魔法数34の出現が確実なものとなった。

We investigate the microscopic origin of ferromagnetism coupled with topological insulators in V-doped (Sb,Bi)$$_{2}$$Te$$_{3}$$ employing X-ray magnetic circular dichroism and angle-resolved two-photon photoemission spectroscopies, combined with first-principles calculations. We found an magnetic moment at the Te site anti-parallel to that of the V and Sb sites, which plays a key role in the ferromagnetic order. We ascribe it to the hybridization between Te 5${it p}$ and V 3${it d}$ majority spin states at the Fermi energy, consistent with the Zener-type ${it p}$-${it d}$ exchange interaction scenario. The substitution of Bi for Sb suppresses the bulk ferromagnetism by introducing extra electron carriers in the majority spin channel of the Te ${it p}$ states that compensates the antiparallel magnetic moment on the Te site. Our findings reveal important clues to designing magnetic topological insulators with higher Curie temperature that work under ambient conditions.

We report the measurement of $$gamma gamma to eta_c(1S)$$, $$eta_c(2S) to eta' pi^+ pi^-$$ with $$eta'$$ decays to $$gamma rho$$ and $$eta pi^+ pi^-$$ using 941 fb$$^{-1}$$ of data collected with the Belle detector at the KEKB asymmetric-energy $$e^+e^-$$ collider. The $$eta_c(1S)$$ mass and width are measured to be $$M = [2984.6pm0.7 (stat.)pm2.2 (syst.)]$$ MeV/$$c^{2}$$ and $$Gamma = [30.8^{+2.3}_{-2.2}~(stat.) pm 2.5~(syst.)]$$ MeV, respectively. First observation of $$eta_c(2S) to eta' pi^+ pi^-$$ with a significance of $$5.5sigma$$ including systematic error is obtained, and the $$eta_c(2S)$$ mass is measured to be $$M = [3635.1pm3.7~(stat.)pm2.9~(syst.)]$$ MeV/$$c^{2}$$. The products of the two-photon decay width and branching fraction $$(B)$$ of decays to $$eta'pi^+ pi^-$$ are determined to be $$Gamma_{gamma gamma}B = [65.4pm2.6~(stat.)pm6.9~(syst.)]$$ eV for $$eta_c(1S)$$ and $$[5.6^{+1.2}_{-1.1}~(stat.)pm1.1~(syst.)]$$ eV for $$eta_c(2S)$$. A new decay mode for the $$eta_c(1S)$$ to $$eta'f_0(2080)$$ with $$f_0(2080) to pi^+ pi^-$$ is observed with a statistical significance of $$20sigma$$. The $$f_0(2080)$$ mass and width are determined to be $$M = [2083^{+63}_{-66}~(stat.)pm 32~(syst.)]$$ MeV/$$c^{2}$$ and $$Gamma = [178^{+60}_{-178}~(stat.) pm 55~(syst.)]$$ MeV. The cross sections for $$gamma gamma to eta' pi^+ pi^-$$ and $$eta'f_{2}(1270)$$ are measured for the first time.

This work demonstrates markedly modified spin dynamics of magnetic insulator (MI) by the spin momentum-locked Dirac surface states of the adjacent topological insulator (TI). As the Bi concentration $$x$$ is systematically tuned in 5-nm-thick (Bi$$_{x}$$Sb$$_{1-x}$$)$$_{2}$$Te$$_{3}$$ TI films, the weight of the surface relative to bulk states peaks at $$x$$ = 0.32 when the chemical potential approaches the Dirac point. At this concentration, the Gilbert damping constant of the precessing magnetization in 10-nm-thick Y$$_{3}$$Fe$$_{5}$$O$$_{12}$$ MI films in the MI/TI heterostructures is enhanced by an order of magnitude, the largest among all concentrations. In addition, the MI acquires additional strong magnetic anisotropy that favors the in-plane orientation with similar Bi concentration dependence. These extraordinary effects of the Dirac surface states distinguish TI from other materials such as heavy metals in modulating spin dynamics of the neighboring magnetic layer.

2017年4月に開催された国際会議Transport2017において、重イオン核反応モデルの国際的な比較が議論された。重イオン加速器の安全評価や宇宙飛行士の被ばく評価等で重要な役割を果たすため、世界中で重イオン核反応の様々な理論モデルが開発されている。本研究はモデル間の共通点と差異を明らかにし、各モデルの問題点を明らかにした。比較において、辺の長さが20fmの直方体に320個の中性子と320個の陽子をランダム配置し、それらが時間発展に伴って起こす散乱の回数や散乱時のエネルギーなどを計算する条件が設定された。また、結果以外にも、理論モデルを構成するアルゴリズムについても比較を行った。発表者は重イオン核反応モデルJQMD(JAERI Quantum Molecular Dynamics)を用いて計算を行い、世界で開発されている15の計算コードによる計算結果と比較した。コードアルゴリズムの比較では、JQMDは必ず陽子から 優先的に衝突確率を計算し、その後に中性子の衝突を計算するため、物理描像の妥当性が指摘された。一方、JQMDは他のモデルとほぼ同じ計算結果を出すことも判明した。衝突回数や運動量の計算値が平均から2倍以上乖離するモデルもある中で、JQMDは本計算条件で安定した性能を発揮することが確認された。

Low-lying states in neutron-rich $$^{81,82.83.84}$$Zn nuclei were measured for the first time via in-beam $$gamma$$-ray spectroscopy at RIKEN. These include the 4$$_1^+$$ to 2$$_1^+$$ in $$^{82}$$Zn and the 2$$_1^+$$ to 0$$_1^+$$ and 4$$_1^+$$ to 2$$_1^+$$ in $$^{84}$$Zn. The reduced E($$2^+$$) energies and increased E(4$$^+$$)/E(2$$^+$$) ratios at $$N$$=52,54 compared to $$^{80}$$Zn attest that the magicity is confined just on the neutron number $$N$$=50 only. The levels observed in $$^{84}$$Zn suggest the onset of deformation towards heavier Zn isotopes. The data were compared to state-of-the-art shell model calculations.

A new high-spin isomer in the neutron-rich nucleus $$^{128}$$Cd was populated in the projectile fission of a $$^{238}$$U beam at the Radioactive Isotope Beam Factory at RIKEN. A half-life of T$$_{1/2}$$ = 6.3(8) ms was measured for the new state which was tentatively assigned a spin/parity of (15$$^-$$). The isomeric state decays via the emission of a 309-keV $$gamma$$ ray with $$E3$$ multipolarity. The experimental results are compared to shell model calculations performed using state-of-the-art realistic effective interactions and to the neighbouring nucleus $$^{129}$$Cd. The comparison with calculations shows that adjustments of the pairing and multipole parts of the effective interaction derived from the CD-Bonn nucleon-nucleon potential are required in order to describe the properties of nuclei in the region around $$^{132}$$Sn.

The first $$gamma$$-ray spectroscopy of very neutron rich $$^{98,100}$$Kr isotopes was carried out at the RIBF at RIKEN Nishina center. Excited states in these isotopes were populated via (p,2p) reactions using radioactive $$^{99,101}$$Rb beams accelerated to 220 MeV/nucleon. The new data show a significant increase in deformation beyond N=60, as well as competing configurations (shape-coexistence) at low energy. The data were compared with beyond-mean-field calculations which predict level energies in good agreement with observation, and suggest oblate-prolate shape coexistence.

Excited states in $$^{133}$$Sn were populated following one-neutron knockout reaction from an unstable $$^{134}$$Sn beam at the RIBF laboratory in RIKEN. In addition to the already known $$gamma$$ rays, additional $$gamma$$ strength was observed for the first time in the excitation-energy range 3.5-5.5 MeV. Since the neutron separation energy of $$^{133}$$Sn is low, this observation provides direct evidence for the radioactive decay of neutron-unbound states in this nucleus. The ability of $$gamma$$ decay to compete with neutron emission was attributed to a mismatch between the wave functions of the initial and final states in the neutron emission case. These findings suggest that in the region south-east of $$^{132}$$Sn, nuclear structure effects play a significant role in the decay of unbound states, which are instead usually ignored in the evaluation of neutron-emission probabilities in astrophysical simulations.

Neutron-rich isotopes of selenium, $$^{88,90,92,94}$$Se, where studied via in beam $$gamma$$-ray spectroscopy after nucleon removal reactions at RIBF in RIKEN. The low-energy excitations of these nuclei were investigated using $$gamma$$-$$gamma$$ coincidences, and the first and second excited 2$$^+$$ states were found at remarkably low energies. The analysis and comparison with self-consistent beyond-mean field calculations suggest that both shape coexistence and triaxiality are needed to describe these isotopes.


Are there signatures of harmonic oscillator shells far from stability?; First spectroscopy of $$^{110}$$Zr

The first measurement of $$gamma$$ rays emitted by the very neutron rich nuclei $$^{112}$$Mo (Z=42) and $$^{110}$$Zr (Z=40) was carried out at the RIBF facility at RIKEN. These data shine light on the postulated N=70 harmonic oscillator shell. If the spin-orbit splitting which gives rise to the N=82 shell gap is reduced in very neutron-rich nuclei, the harmonic oscillator gap at N=70 should open instead. However, both the measured energy of the first excited state $$^{112}$$Mo and $$^{110}$$Zr, respectively 235(7) keV and 185(11) keV, and their E(4$$^+$$)/E(2$$^+$$) ratio, indicate that these nuclei are good rotors, and exclude the shell stabilization scenario at Z=40 and N=70. These results were compared to state-of-the-art density functional theoretical calculations using Gogny and Skyrme effective interactions.

The $$beta$$ decay of the semi-magic nucleus $$^{130}$$Cd has been studied at the RIBF facility at the RIKEN Nishina Center. The high statistics of the present experiment allowed for a revision of the established level scheme of $$^{130}$$In and the observation of additional $$beta$$ feeding to high lying core-excited states in $$^{130}$$In. The experimental results are compared to shell-model calculations employing a model space consisting of the full major $$N=50-82$$ neutron and $$Z=28-50$$ proton shells, and good agreement is found.

近年、大強度加速器施設におけるビーム高強度化を実現するため、強い放射線環境下で安定に高磁場を形成可能な超伝導磁石システムが求められている。本研究では、大型ハドロン衝突型加速器(Large Hadron Collider: LHC)の高輝度化アップグレード計画において、数十MGy級の耐放射線性を有するビーム分離用双極超伝導磁石システム(D1システム)を開発することを目指している。このシステムには超伝導材料や電気絶縁材料が用いられるが、電気絶縁材料にはコイル線材間の隙間を埋める成形性と十分な耐放射線性が要求される。我々は高い成形性、放射線照射時の低分解ガス生成能と高強度維持を実現したガラス繊維強化ビスマレイミドトリアジン(BT)樹脂を開発した。従来のガラス繊維強化エポキシ(G10)樹脂の場合、10MGyの$$gamma$$線照射後、4$$times$$10$$^{-5}$$mol/gのガスが発生し、曲げ強度が初期値の60%である280MPaまで低下したのに対し、BTでは100MGyの$$gamma$$線照射後、5$$times$$10$$^{-5}$$mol/gのガス発生量と初期値の90%である640MPaの曲げ強度を示した。今後、NbTi系超伝導線材の開発と磁石デザインを行ない、D1システム用モデル磁石を製作する予定である。

The $$beta$$ decay of $$^{129}$$Cd, produced in relativistic fission of a $$^{238}$$U beam, was studied at the RIKEN Nishina Center. From the $$gamma$$-ray analysis, 31 excited states and 69 $$gamma$$ ray transitions were established in the level scheme of $$^{129}$$In, and compared with state-of-the-art shell-model calculations. It was found that the $$beta$$ decay of $$^{129}$$Cd is dominated by Gamow teller transitions, but a non-negligible contribution to the $$beta$$ decay is also made by first-forbidden transitions. To estimate the contribution of first-forbidden transitions is important for calculations of the $$beta$$-decay half-lives of nuclei in this region.

The $$beta$$-decay half-lives of 110 neutron-rich isotopes of the elements from Rb to Sn were measured at the RIBF Facility at RIKEN, Japan. The new data demonstrate the persistence of shell structure far from stability and have direct implications for the $$r$$-process calculations. In particular, the new half-lives have a global impact on the calculated $$r$$-process elemental abundances, and alleviate the underproduction of isotopes just above and below the A=130 peak, which in the past required the introduction of shell structure modifications. Reaction-network calculations based on the new data reinforce the notion that the r-process abundance pattern may result from the freeze-out of a (n,$$gamma$$)$$_leftarrow^{rightarrow}$$($$gamma$$,n) equilibrium.
