Systematic shell-model study for structure and isomeric states in 200−210Po isotopes

Abstract

We report systematic large-scale shell-model calculation for Po isotopes with A= 200 to 210. We have performed calculations using KHH7B interaction in the model space Z = 58-114 and N = 100-164 around doubly-magic ²⁰⁸Pb. We allow valence neutrons to occupy in the $1f_{5/2}$, $2p_{3/2}$, $2p_{1/2}$, and $0i_{13/2}$ orbitals, while two valence protons beyond $Z=82$ are occupied in $0h_{9/2}$, $1f_{7/2}$ and $0i_{13/2}$ orbitals. The calculated energies and electromagnetic properties are compared with the available experimental data and predicted where experimental data are not available. We have also reported shell-model results for different isomeric states of these nuclei.
