Microscopic structure calculations in Ru, Pd and Cd nuclei

Abstract

Nuclear structure calculations for Ru, Pd and Cd isotopes are performed in a large configuration space by applying the quadrupole-plus-pairing interaction Hamiltonian. It is found the the large deformations in the neutron-rich isotopes are accompanied by a substantial increase in the occupancy of the 0h11/2 neutron orbital. The energy spectra and the B(E2) values in the deformed nuclei are calculated in the variation-after-projection formalism with angular momentum projection and nucleon number conservation in each state. The results of the calculations are in fair agreement with the corresponding experimental data.
