Structure of medium-mass nuclei studied by Monte Carlo shell model calculations

ORAL

Abstract

We have studied medium-mass nuclei of various regions by Monte Carlo shell model (MCSM) calculations. Our MCSM calculations for Ni isotopes reproduce well their properties such as levels and transitions. Shape coexistence of nuclei around 68Ni is predicted by the calculations. Neutron-rich nuclei around N=50 are calculated by using extended model space and shape coexistence of 78Ni is predicted. In this talk, we discuss structure and beta-decay property of neutron-rich nuclei around N=50.
