Description

We study Cr and Ni isotopes by using Monte Carlo shell model (MCSM) calculations in a pfg9d5 model space which consists of the 0f1p shell, 0g9/2 and 1d5/2 orbits, in order to treat magic numbers 28, 50 and a sub-magic number 40. In MCSM, a wave function is represented as a linear combination of angular-momentum- and parity-projected deformed Slater determinants (MCSM bases) and we can obtain eigenstates in a large model space such as pfg9d5 space. We showed the change of N=40 magic behaviour in Cr and Ni isotopes and three 0+ states of 68Ni with different shapes and close energies. The calculated excitation energies of 68Ni reproduce experimental values including non-yrast and negative-parity states
