- Abstract
In this paper, we study yrast states of two N = 126 isotones 210 Po and 212 Rn using the nucleon-pair approximation with particle–hole excitations and using a low-momentum interaction V low – k renormalized from the free CD-Bonn N N potential. An overall good agreement with experimental level structures, B (E 2) s, and B (E 3) s, is achieved. We also calculate the probabilities of neutron particle–hole excitations in these yrast states, with a focus on negative-parity states, which reflect the roles played by the neutron negative-parity configurations of one-particle-one-hole excitations across the N = 126 shell gap and the negative-parity configurations of valence proton particles involving the 0 i 13 / 2 orbit. The N = 126 shell gap is discussed in terms of energies of neutron one-particle-one-hole excitations.
