Understanding Excitations in Co, Ni
Samuel Ajayi, Vandana Tripathi, E. Rubino +10
High spin states in Co (), Ni () and Co have been populated by the fusion evaporation reactions, Ti(C, p2n)Co, Ti($^{14…
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…
Structure of Mg explored via in-beam -ray spectroscopy
N. Kitamura, K. Wimmer, N. Shimizu +18
Background: In the "island of inversion", ground states of neutron-rich -shell nuclei exhibit strong admixtures of intruder configurations from the shell. The nucleus $^{3…
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…
