Spontaneous fission half-life in Fm isotopes with nuclear energy density functional
Kouhei Washiyama
A microscopic description of fission dynamics is important to understand the decay properties of neutron-rich heavy nuclei that are relevant to -process nucleosynthesis. To prov…
Five-dimensional collective Hamiltonian with improved inertial functions
Kouhei Washiyama, Nobuo Hinohara, Takashi Nakatsukasa
Background: To describe shape fluctuations associated with large-amplitude collective motion in the quadrupole degrees of freedom, the five-dimensional collective Hamiltonian (5DCH…
Evolution of giant monopole resonance with triaxial deformation
Kouhei Washiyama, Shuichiro Ebata, Kenichi Yoshida
Background: The isoscalar giant monopole resonance (ISGMR) splits into two peaks in prolately deformed nuclei. When a nucleus is triaxially deformed, a peak appears in the middle b…
Triaxial-shape dynamics in the low-lying excited state: Role of the collective mass
Kouhei Washiyama, Kenichi Yoshida
Background: Non-yrast states in neutron-rich nuclei are being investigated experimentally. These states reveal various aspects and details of the nuclear structure, such as the flu…
Finite-amplitude method for collective inertia in spontaneous fission
Kouhei Washiyama, Nobuo Hinohara, Takashi Nakatsukasa
Background: Microscopic description of spontaneous fission is one of the most challenging subjects in nuclear physics. It is necessary to evaluate the collective potential and the…
TDHF and a macroscopic aspect of low-energy nuclear reactions
Kouhei Washiyama, Kazuyuki Sekizawa
Time-dependent Hartree--Fock (TDHF) method has been applied to various low-energy nuclear reactions, such as fusion, fission, and multinucleon transfer reactions. In this Mini Revi…
