Generalized seniority isomers in and around Z = 82 closed shell: a survey of Hg, Pb and Po isotopes

Abstract

In this paper, we investigate the generalized seniority scheme and the validity of Generalized Seniority Schmidt Model in and around the Z = 82 semi-magic region. A consistently same multi-j configuration is used to explain all the nuclear spectroscopic properties such as g−factors, Q−moments and B(E2) trends for the 13/2+, 12+ and 33/2+ isomers in all the three Hg, Pb and Po isotopic chains. The inverted parabolic B(E2) trends for the first 2+ states in Hg, Pb and Po isotopes are also explained using the generalized seniority scheme. A comparison with the experimental data is presented, wherever possible, and future possibilities are suggested.
