Theoretical investigation of nuclear structure and shape evolution in even–even Gd isotopes with A = 152–160

In the present work, a theoretical attempt using triaxial projected shell model (TPSM) has been made to understand and confirm the structural evolution observed in even–even isotopes (A = 152–164) of Gd (\(Z=64\)) nucleus. The TPSM study of yrast, \(\gamma\), \(\gamma \gamma\)-bands provides a reasonable description about the triaxial nature of these isotopes. The E-GOS plots along with \(R_{42}\)-ratios predict shape transition phenomenon along isotopic chain under study. Further, backbending in moment of inertia, g factors, transition probabilities, energy staggering in \(\gamma\)-bands, etc., have also been calculated and found to be in good agreement with the available experimental data.
