• High-spin structure of yrast-band in 78Kr

Lifetime of levels up to 22+, have been measured in 78Kr and an oblate shape is assigned to the ground state using the CSM and the configuration dependent shell correction calculations. Calculations further show that 78Kr is highly γ-soft nucleus. The experimental Qt values coupled with theoretical calculations indicate an oblate shape for 78Kr at low spins and triaxial shape at higher spins

• Structure of 72,74Se at high spin

Lifetimes of high spin states up to {$$I^\pi$$}=22+ in the yrast positive parity bands have been measured to investigate the shape evolution with increasing spin in 72, 74Se. The Qt values derived from these measurements indicate that prolate shape stabilizes for 72Se, while a triaxial shape develops for 74Se at higher spins. Comparison of the observed trend in Qt with spin for 72, 74Se with that of the corresponding kryptones isotones emphasizes the stability provided by N=38 prolate shell gap even at high rotational frequency.
