Quasiparticle structure of low-lying yrast energy levels and $$\gamma $$ γ -bands in $$^{164{-}174}$$ 164 - 174 Hf nuclei

In the present work, we have employed the theoretical framework of Triaxial Projected Shell Model (TPSM) to investigate the presence of triaxiality in transitional nuclei of $$^{164{-}174}$$ Hf. We have obtained the calculated yrast and $$\gamma $$ -bands and compared with the corresponding experimental data. In addition to these, $$\gamma \gamma $$ -bands are also predicted. In order to thoroughly understand the structure of yrast and $$\gamma $$ -bands, we have kept our focus to study low energy states. The yrast energy ratios, staggering in $$\gamma $$ -bands, the phenomenon of back-bending, the reduced electromagnetic transition probabilities and g-factors are calculated using TPSM.
