Semiclassical description of quadrupole-hexadecapole correlation in nuclear shape evolution
Kenichiro Arita
Background: Theoretical investigations of nuclear shapes with realistic effective interactions or mean field potentials have suggested a remarkable systematics in the hexadecapole…
Classical periodic orbits in extended phase space for spherical harmonic oscillator with spin-orbit coupling
Kenichiro Arita
A complete analysis of classical periodic orbits (POs) and their bifurcations was conducted in spherical harmonic oscillator system with spin-orbit coupling. The motion of the spin…
Semiclassical origin of nuclear ground-state octupole deformations
Ken-ichiro Arita
Background: Ground-state octupole deformations are suggested in nuclei located in the north-east neighbor of the doubly magic nuclei on the nuclear chart (N,Z), such as those in Ba…
Octupole deformation of nuclei near the spherical closed-shell configurations
Ken-ichiro Arita
The origin of octupole deformation for even-even nuclei near the doubly-closed shell configurations are investigated by means of the semiclassical periodic orbit theory. In order t…
Semiclassical origin of asymmetric nuclear fission: Nascent-fragment shell effect in periodic-orbit theory
K. Arita, T. Ichikawa, K. Matsuyanagi
The origin of the asymmetry in the fragment mass distribution of low-energy nuclear fission is considered from the semiclassical point of view. Using the semiclassical periodic-orb…
Nascent fragment shell effects on the nuclear fission processes in semiclassical periodic orbit theory
Ken-ichiro Arita, Takatoshi Ichikawa, Kenichi Matsuyanagi
Making use of the semiclassical periodic orbit theory (POT), we propose, for the first time, a method to exclusively evaluate the shell effects associated with each of the nascent…
