Abstract :
Lifetimes have been measured up to the I=22+ level in the yrast positive-parity band for 78Kr using the recoil distance and lineshape analysis methods. The B(E2) and Qt values obtained from these measurements show a significant drop with increasing spin. The band crossings and the observed variation in Qt are understood through cranked shell-model, TRS and configuration-dependent shell-correction calculations assuming an oblate deformation for 78Kr at low spins.
