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…
Two-particle transfer processes as a signature of shape phase transition in Zirconium isotopes
J. A. Lay, A. Vitturi, L. Fortunato +3
We explore two-particle transfer reactions as a unique probe of the occurence of shape coexistence in shape phase transitions. The (t,p) reactions to the ground state and to excite…
Evidence for coexisting shapes in Zr through lifetime measurements
Purnima Singh, W. Korten, T. W. Hagen +35
The lifetimes of first excited 2, 4 and 6 states in Zr were measured with the Recoil-Distance Doppler Shift method in an experiment performed at GANIL. Excited s…
Uncertainty quantification in nuclear shell model
Sota Yoshida, Noritaka Shimizu, Tomoaki Togashi +1
The uncertainty quantifications of theoretical results are of great importance to make meaningful comparisons of those results with experimental data and to make predictions in exp…
Novel shape evolution in Sn isotopes from magic numbers 50 to 82
Tomoaki Togashi, Yusuke Tsunoda, Takaharu Otsuka +2
A novel shape evolution in the Sn isotopes by the state-of-the-art application of the Monte Carlo Shell Model calculations is presented in a unified way for the 100-138Sn isotopes.…
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…
Quantum self-organization and nuclear collectivities
T. Otsuka, Y. Tsunoda, T. Togashi +2
The quantum self-organization is introduced as one of the major underlying mechanisms of the quantum many-body systems, for instance, atomic nuclei. It is shown that atomic nuclei…
First Measurement of Collectivity of Coexisting Shapes based on Type II Shell Evolution: The Case of Zr
C. Kremer, S. Aslanidou, S. Bassauer +13
Background: Type II shell evolution has recently been identified as a microscopic cause for nuclear shape coexistence. Purpose: Establish a low-lying rotational band in 96-Zr. Meth…
Quantum Phase Transition in the Shape of Zr isotopes
Tomoaki Togashi, Yusuke Tsunoda, Takaharu Otsuka +1
The rapid shape change in Zr isotopes near neutron number =60 is identified to be caused by type II shell evolution associated with massive proton excitations to its …
Large-scale shell-model calculations for unnatural-parity high-spin states in neutron-rich Cr and Fe isotopes
Tomoaki Togashi, Noritaka Shimizu, Yutaka Utsuno +2
We investigate unnatural-parity high-spin states in neutron-rich Cr and Fe isotopes using large-scale shell-model calculations. These shell-model calculations are carried out withi…
Recent Advances in Shell Evolution with Shell-Model Calculations
Yutaka Utsuno, Takaharu Otsuka, Yusuke Tsunoda +4
Shell evolution in exotic nuclei is investigated with large-scale shell-model calculations. After presenting that the central and tensor forces produce distinctive ways of shell ev…
