Study of yrast bands and electromagnetic properties in neutron-rich 114–128Cd isotopes

The projected shell model framework has been employed to carry out a systematic study on the deformation systematics of E(21+) and E(41+)/E(21+) values, BCS subshell occupation numbers, yrast spectra, backbending phenomena and electromagnetic quantities in 114–128Cd isotopes. Present calculations re...

Description
Summary:The projected shell model framework has been employed to carry out a systematic study on the deformation systematics of E(21+) and E(41+)/E(21+) values, BCS subshell occupation numbers, yrast spectra, backbending phenomena and electromagnetic quantities in 114–128Cd isotopes. Present calculations reproduce the observed systematics of the E(21+), R42 and B(E2;2+→0+) values for 114–128Cd isotopic mass chain and give the evidence that deformation increases as one moves from 114Cd to 118Cd, thereafter it decreases up to 126Cd. This in turn confirms 118Cd to be the most deformed nucleus in this set of isotopic mass chain. The emergence of backbending, decrease in B(E2) values and change in g-factors in all these isotopes are intimately related to the crossing of g-band by 2-qp bands.
