Microscopic investigation of $E2$ matrix elements in atomic nuclei -- II
Abstract
The present work is a continuation of our earlier investigation with the primary objective to systematically calculate the matrix elements using the microscopic approach of the triaxial projected shell model (TPSM). In the earlier work, we studied nine nuclides of Ge, Ge, Ru, Er, Os, Os, Os, Os, and Pt. In the present work six more nuclides of Ge, Se, and Mo have been investigated. The Coulomb excitation data has recently become available for Ge and other nuclides were inadvertently omitted in our earlier investigation. It is demonstrated that TPSM approach provides a good description of the available experimental data and most of the nuclides, except for Se and Mo, are shown to have soft behaviour. Further, it is demonstrated that in contrast to the predictions of the phenomenological collective model, TPSM calculations depict no clear correlation between the energy staggering pattern of the band and the deduced shape invariant quantities using the Kumar-Cline sum rules.
