Nuclear Mass Dependence of Chaotic Dynamics in Ginocchio Model
Naotaka Yoshinaga, Nobuaki Yoshida, Takaomi Shigehara +1
The chaotic dynamics in nuclear collective motion is studied in the framework of a schematic shell model which has only monopole and quadrupole degrees of freedom. The model is sho…
Statistical properties of antisymmetrized molecular dynamics for non-nucleon-emission and nucleon-emission processes
Akira Ono, Hisashi Horiuchi
Statistical properties of the antisymmetrized molecular dynamics (AMD) are classical in the case of nucleon emission processes, while they are quantum mechanical for the processes…
On the nature of nuclear dissipation, as a hallmark for collective dynamics at finite excitation
Helmut Hofmann, Fedor A. Ivanyuk, Shuhei Yamaji
We study slow collective motion of isoscalar type at finite excitation. The collective variable is parameterized as a shape degree of freedom and the mean field is approximated by…
Improvement of the nucleon emission process and the statistical property in molecular dynamics
Akira Ono, Hisashi Horiuchi
We propose to introduce a new stochastic process in molecular dynamics in order to improve the description of the nucleon emission process from a hot nucleus. We give momentum fluc…
Precise solution of few-body problems with stochastic variational method on correlated Gaussian basis
K. Varga, Y. Suzuki
Precise variational solutions are given for problems involving diverse fermionic and bosonic -body systems. The trial wave functions are chosen to be combinations of correla…
Direct radiative capture of p-wave neutrons
A. Mengoni, T. Otsuka, M. Ishihara
The neutron direct radiative capture (DRC) process is investigated, highlighting the role of incident p-wave neutrons. A set of calculations is shown for the 12-C(n,gamma) process…
