Low-lying states of Hg isotopes within the nucleon pair approximation

Abstract

The low-lying states of 200–205Hg nuclei have been studied by using the nucleon pair approximation (NPA) of the shell model. We calculate low-excited energy levels, electric quadrupole moments, and magnetic dipole moments, and investigate dominant configurations of low-lying states in the nucleon pair basis. Our calculations reasonably reproduce the available experimental data. We also tabulate our predicted results of low-lying states, including excitation energies, electric quadrupole moments and magnetic moments.
