High-spin states of $$^{190}$$Pt have been reinvestigated using the $$^{176}$$Yb($$^{18}$$O, 4$$n$$) reaction at a beam energy of 88 MeV. The previously known positive parity band associated with the $$nu$$ $$i^{-2}_{13/2}$$ $$nu$$ $$h^{-1}_{9/2}$$ $$nu$$ $$j^{-1}$$ ($$nu j$$ being $$nu p_{3/2}$$ or $$nu f_{5/2}$$) configuration has been revised and extended significantly. A new negative parity band has been established and proposed to be based on the $$nu$$ $$i^{-3}_{13/2}$$ $$nu$$ $$j^{-1}$$ configuration. Possible structure evolution of the yrast line from predominantly vibrational to rotational with increasing spin is discussed with the help of E$$_gamma$$ over spin curves. Additionally, calculations of Total Routhian surfaces have been performed to investigate the band properties.

Actively circulated liquid metal divertor (ACLMD)

Shimada, Michiya; Hirooka, Yoshihiko*; Zhou, H.*

Europhysics Conference Abstracts (Internet), 38F, p.O2.110_1 - O2.110_4, 2014/00

Tungsten is considered to be most promising candidate for divertor target material for fusion reactor. Although tungsten target can withstand the heat loads of ITER, the heat exhaust requirement for DEMO is much more demanding. Pulsive heat loads associated with disurption would melt the tungsten divertor target. Melting and subsequent resolidification will roughen the tungsten surface, significantly deteriorating the heat handling capability. Further, tungsten has a rather high DBTT (Ductile-Brittle-Transition temperature) of 400$$^{circ}$$C. Neutron irradiation would further increase the DBTT, which could result in cracks. In view of these issues, liquid metal divertor is proposed, which is actively circulated with the Lorentz force introduced through the electrodes in the liquid metal. A modest flow speed of 0.3 m/s seems to be adequate for the heat load exhaust of DEMO. A simple treatment of MHD equation in a cylindrical geometry suggests that the requirements on the current and voltage are modest if the ramp-up of current is made slowly (e.g. in a minute), implying that the this concept is worth further study.

High-spin states in $$^{101}$$Pd have been investigated by means of in-beam $$gamma$$-ray spectroscopic techniques. The previously known $$d$$$$_{5/2}$$ and 1/2$$^-$$[550] bands were extended to higher spins. The band crossings observed experimentally are explained by the alignment of $$g$$$$_{9/2}$$ protons. The band properties in $$^{101}$$Pd are compared with those in the neighboring nuclei and are discussed within the framework of the cranked shell model.

High-spin states in $$^{185}$$Pt have been investigated by means of in beam $$gamma$$-ray spectroscopic method at the JAEA tandem facility. Low-spin signature inversion is revealed in the 7/2$$^-$$[503] band. The inversion can be interpreted as a configuration change from the 7/2$$^-$$[503] orbital to the 7/2$$^-$$[514] orbital with increasing spin, which is supported by a theoretical calculation of the semi-classical Donau and Frauendorf approach.

We report on the event structure and double helicity asymmetry ($$A_{LL}$$) of jet production in longitudinally polarized $$p + p$$ collisions at $$sqrt{s}$$ = 200 GeV. Photons and charged particles were measured by the PHENIX experiment. Event structure was compared with the results from PYTHIA event generator. The production rate of reconstructed jets is satisfactorily reproduced with the next-to-leading-order perturbative QCD calculation. We measured $$A_{LL}$$ = -0.0014 $$pm$$ 0.0037 at the lowest $$P_T$$ bin and -0.0181 $$pm$$ 0.0282 at the highest $$P_T$$ bin. The measured $$A_{LL}$$ is compared with the predictions that assume various $$Delta G(x)$$ distributions.

Transverse momentum distributions and yields for $$pi^{pm}, K^{pm}, p$$, and $$bar{p}$$ in $$p + p$$ collisions at $$sqrt{s}$$ = 200 and 62.4 GeV at midrapidity are measured by the PHENIX experiment at the RHIC. We present the inverse slope parameter, mean transverse momentum, and yield per unit rapidity at each energy, and compare them to other measurements at different $$sqrt{s}$$ collisions. We also present the scaling properties such as $$m_T$$ and $$x_T$$ scaling and discuss the mechanism of the particle production in $$p + p$$ collisions. The measured spectra are compared to next-to-leading order perturbative QCD calculations.

Azimuthal correlations of electrons from heavy-flavor decay with hadrons in $$p+p$$ and Au+Au collisions at $$sqrt{s_{NN}}$$ = 200 GeV

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled $$p+p$$ collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to $$p+p$$ collisions.

The PHENIX experiment at RHIC has measured the invariant differential cross section for production of $$K^0_s$$, $$omega$$, $$eta'$$ and $$phi$$ mesons in $$p + p$$ collisions at $$sqrt{s}$$ = 200 GeV. The spectral shapes of all hadron transverse momentum distributions are well described by a Tsallis distribution functional form with only two parameters, $$n$$ and $$T$$, determining the high $$p_T$$ and characterizing the low $$p_T$$ regions for the spectra, respectively. The integrated invariant cross sections calculated from the fitted distributions are found to be consistent with existing measurements and with statistical model predictions.

Chinese Physics Letters, 24(5), p.1203 - 1206, 2007/05

High-spin states in $$^{174}$$Re are investigated via in-beam $$gamma$$-ray spectroscopic method and $$gamma - gamma$$ coincidence relationships are analysed. A new band is identified due to its spectroscopic connection with the known $$pi 1/2^-[541] bigotimes nu 1/2^-[521]$$ band. This band is proposed to be the ground-state band built on the $$pi 1/2^-[541] bigotimes nu 5/2^-[512]$$ configuration in view of the low-lying intrinsic states in neighbouring odd-mass nuclei. It is in particular interesting that the new band exhibits a phenomenon of low-spin signature inversion, providing a new situation for theoretical investigations.

An experiment for the laser self-guiding studies has been carried out with 100 TW laser pulse interaction with the long underdense plasma. Formation of extremely long plasma channel with its length, about 10 mm, 20 times above the Rayleigh length is observed. The self-focusing channel features such as the laser pulse significant bending and the electron cavity formation are demonstrated experimentally for the first time.

High-spin states in $$^{187}$$Pt has been studied experimentally by in-beam $$gamma$$-ray spectroscopy. The previously known bands based on the $$nu i_{13/2}, nu 7/2^{-}[503] $$ and $$nu i^{2}_{13/2} nu j$$ configurations have been extended to high-spin states, and new rotational bands associated with the $$nu 3/2^{-}[512]$$ and $$nu 1/2^{-}[521]$$ Nilsson orbits have been identified. The total Routhian surface calculations indicate that the transitional nucleus $$^{187}$$Pt is very soft with respect to $$beta$$ and $$gamma$$ deformations. The band properties have been compared with the systematics observed in neiboring nuclei and have been interpreted within the framework of the cranked shell model.

Search for low-spin signature inversion in the $$pi i_{13/2} bigotimes nu i_{13/2}$$ bands in odd-odd $$^{182,184,186}$$Au have been made through in-beam $$gamma$$-ray spectroscopy techniques. The $$pi i_{13/2} bigotimes nu i_{13/2}$$ bands in the three nuclei have been identified and extended up to high-spin states. In particlular, the interband connection between the $$pi i_{13/2} bigotimes nu i_{13/2}$$ band and the ground-state band in $$^{184}$$Au have been established, leading to a firm spin-and-parity assignment for the $$pi i_{13/2} bigotimes nu i_{13/2}$$ band. The low-spin signature inversion is found in the $$pi i_{13/2} bigotimes nu i_{13/2}$$ bands in $$^{182,184,186}$$Au.

Excited states in $$^{188}$$Tl have been studied experimentally by in-beam $$gamma$$-ray spectroscopy. A rotational band built on the $$pi rm h_{9/2} bigotimes nu rm i_{13/2}$$ configuration with oblate deformation has been established for $$^{188}$$Tl. Based on the structure systematics of the oblate $$pi rm h_{9/2} bigotimes nu rm i_{13/2}$$ bands in heavier odd-odd Tl nuclei, we have tentatively proposed spin values for the new band in $$^{188}$$Tl. The new oblate band shows low-spin signature inversion, and it can be interpreted qualitatively by the two-quasiparticle plus rotor model including a $$J$$-dependent $$p$$-$$n$$ residual interaction.
