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…
Microscopic derivation of the Bohr-Mottelson collective Hamiltonian and its application to quadrupole shape dynamics
Kenichi Matsuyanagi, Masayuki Matsuo, Takashi Nakatsukasa +3
We discuss the nature of the low-frequency quadrupole vibrations from small-amplitude to large-amplitude regimes. We consider full five-dimensional quadrupole dynamics including th…
Time-dependent density-functional description of nuclear dynamics
Takashi Nakatsukasa, Kenichi Matsuyanagi, Masayuki Matsuo +1
We present the basic concepts and recent developments in the time-dependent density functional theory (TDDFT) for describing nuclear dynamics at low energy. The symmetry breaking i…
Quantal rotation and its coupling to intrinsic motion in nuclei
Takashi Nakatsukasa, Kenichi Matsuyanagi, Masayuki Matsuzaki +1
Symmetry breaking is an importance concept in nuclear physics and other fields of physics. Self-consistent coupling between the mean-field potential and the single-particle motion…
Microscopic derivation of the quadrupole collective Hamiltonian for shape coexistence/mixing dynamics
Kenichi Matsuyanagi, Masayuki Matsuo, Takashi Nakatsukasa +3
Assuming that the time-evolution of the self-consistent mean field is determined by five pairs of collective coordinate and collective momentum, we microscopically derive the colle…
