Gamow-Teller transitions of neutron-rich nuclei by shell-model calculations
Noritaka Shimizu, Tomoaki Togashi, Yutaka Utsuno
-decay half-lives of neutron-rich nuclei around are key data to understand the -process nucleosynthesis. We performed large-scale shell-model calculations in this regi…
Variational approach with the superposition of the symmetry-restored quasi-particle vacua for nuclear shell-model calculations
Noritaka Shimizu, Yusuke Tsunoda, Yutaka Utsuno +1
We propose a variational calculation scheme utilizing the superposition of the angular-momentum, parity, number projected quasiparticle vacua, that is especially suitable for apply…
Thick-Restart Block Lanczos Method for Large-Scale Shell-Model Calculations
Noritaka Shimizu, Takahiro Mizusaki, Yutaka Utsuno +1
We propose a thick-restart block Lanczos method, which is an extension of the thick-restart Lanczos method with the block algorithm, as an eigensolver of the large-scale shell-mode…
Novel approach to excitation spectrum from correlated ground state
Takaharu Otsuka, Tomoaki Togashi, Noritaka Shimizu +2
A novel approach to obtain the excitation spectrum of nuclei is presented as well as its proof-of-principle. The Monte Carlo Shell Model is extended so that the excitation spectrum…
Evolution of shell structure in exotic nuclei
Takaharu Otsuka, Alexandra Gade, Olivier Sorlin +2
The atomic nucleus is a quantum many-body system whose constituent nucleons (protons and neutrons) are subject to complex nucleon-nucleon interactions that include spin- and isospi…
Non-coherent character of isoscalar pairing probed with Gamow-Teller strength: New insight into C dating decay
Yutaka Utsuno, Yoshitaka Fujita
We investigate the phase coherence of isoscalar pairs from the values in two-particle configurations of , 18, and 42 nuclei and…
