摘要：
A systematic study of the nuclear observables related to the triaxial nature of the even-even( 104-122)Cd isotopes is presented microscopically using multi-quasiparticle triaxial projected shell model (TPSM) approach. In the present work, we have performed a detailed study of gamma-bands in cadmium isotopes in addition to the yrast band. The present calculations are found to reproduce the observed systematics of the R-42 = [E(4(1)(+))/E(2(1)(+))], E-GOS plots and B(E2) values for Cd104-122 isotopic mass chain. The EGOS plots along with the R-42 ratios predict the quasi-deformed structure for these bands. Besides this, odd-even staggering in gamma bands, inter band and intra band reduced transition probabilities and g-factors have also been discussed in the present work and it is shown that TPSM approach provides a reasonable description of the measured properties.
