Nucleon and $$Delta$$ isobar in a strong magnetic field

We investigate Skyrmion solution of the chiral Lagrangian with magnetic field. We find that the Skyrmion is deformed in the magnetic field and its mass increases accordingly. The nucleon and $$Delta$$ isobar states are considered in the Skyrme model.

"$$K^-pp$$", a $$bar K$$-meson nuclear bound state, observed in $$^3$$He($$K^-,Lambda p)n$$ reactions

Hashimoto, Tadashi; Tanida, Kiyoshi; 67 of others*

We observed a distinct peak in the $$Lambda p$$ invariant mass spectrum of $$^{3}{rm He}(K^-, , Lambda p)n$$, well below $$m_K + 2m_p$$, $$i.e.$$, the mass threshold of the $$K^-$$ to be bound to two protons. By selecting a relatively large momentum-transfer region $$q = 350 sim650$$ MeV/$$c$$, one can clearly separate the peak from the quasi-free process,$$overline{K}N rightarrow overline{K}N$$ followed by the non-resonant absorption by the non-resonant absorption by the two spectator-nucleons $$overline{K}NN rightarrow Lambda N$$. We found that the simplest fit to the observed peak gives us a Breit-Wignerpole position at $$B_{rm {it Kpp}} = 47 pm 3 , (stat.) ,^{+3}_{-6},(sys.)$$ MeV having a width $$Gamma_{rm {it Kpp}} = 115 pm 7 , (stat.),^{+10}_{-20} ,(sys.)$$ MeV, and the $$S$$-wave Gaussian reaction form-factor parameter $$Q_{rm {it Kpp}} = 381 pm 14 , (stat.),^{+57}_{-0} ,(sys.)$$MeV/$$c$$, as a new form of the nuclear bound system with strangeness -"$$K^-pp$$".

Role of multichance fission in the description of fission-fragment mass distributions at high energies

Hirose, Kentaro; Nishio, Katsuhisa; Tanaka, Shoya*; L$'e$guillon, R.*; Makii, Hiroyuki; Nishinaka, Ichiro*; Orlandi, R.; Tsukada, Kazuaki; Smallcombe, J.*; Vermeulen, M. J.; et al.

Fission-fragment mass distributions were measured for $$^{237-240}$$U, $$^{239-242}$$Np and $$^{241-244}$$Pu populated in the excitation-energy range from 10 to 60 MeV by multi-nucleon transfer channels in the reaction $$^{18}$$O + $$^{238}$$U at the JAEA tandem facility. Among them, the data for $$^{240}$$U and $$^{240,241,242}$$Np were observed for the first time. It was found that the mass distributions for all the studied nuclides maintain a double-humped shape up to the highest measured energy in contrast to expectations of predominantly symmetric fission due to the washing out of nuclear shell effects. From a comparison with the dynamical calculation based on the fluctuation-dissipation model, this behavior of the mass distributions was unambiguously attributed to the effect of multi-chance fission.

Dispersive coupled-channel analysis of nucleon scattering from $$^{232} $$Th up to 200 MeV

Soukhovitskij, E. Sh.*; Capote, R.*; Quesada, J. M.*; Chiba, Satoshi

Lane consistent coupled channels optical model potential (OMP) containing a dispersive term including nonlocal contribution is used to simultaneously fit the available experimental database (including strength functions and scattering radius) for neutron and proton scattering on strongly deformed $$^{232}$$Th nucleus. The energy range 0.001-200 MeV is covered. A dispersive coupled-channel optical model (DCCOM) potential with parameters that show a smooth energy dependence and energy independent geometry are determined from fits to the entire data set. Dispersive contribution is shown to be the dominant Coulomb correction to the proton real potential below the Coulomb barrier. Inclusion of nonlocality effects in the absorptive volume potential and its corresponding dispersive contribution to the real potential is needed to achieve an excellent agreement above 100 MeV.

In-beam $$gamma$$-ray spectroscopy of $$^{240}$$U using the ($$^{18}$$O,$$^{16}$$O) reaction

Ishii, Tetsuro; Shigematsu, Soichiro; Asai, Masato; Makishima, Akiyasu*; Matsuda, Makoto; Kaneko, Junichi*; Hossain, I.*; Ichikawa, Shinichi; Kono, Toshiyuki*; Ogawa, Masao*

In the two-neutron-transfer reaction of a 200-MeV $$^{18}$$O beam with a $$^{238}$$U target, deexcitation $$gamma$$ rays in a neutron-rich nucleus of $$^{240}$$U were measured. The $$gamma$$ rays in $$^{240}$$U were identified by taking coincidence with $$^{16}$$O, using Si $$Delta E$$-$$E$$ detectors. The kinetic energies of $$^{16}$$O particles allowed us to select the excitation energies of $$^{240}$$U below the neutron separation energy. The ground-state band and the $$K^{pi}=0^{-}$$ octupole band of $$^{240}$$U were established up to 12$$^{+}$$ and 9$$^{-}$$, respectively. The octupole-band head of $$^{240}$$U is higher than those of $$^{236,238}$$U by about a hundred keV, suggesting that a secondary maximum of octupole correlations exists at $$N=144-146$$ in U isotopes.
