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 1f5/2, 2p3/2, 2p1/2, and 0i13/2 orbitals, while two valence protons beyond Z=82 are occupied in 0h9/2, 1f7/2 and 0i13/2 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.
