Abstract

The transition rates from the yrast 2(+) and 4(+) states in the self-conjugate Kr-72 nucleus were studied via lifetime measurements employing the GRETINA array with a novel application of the recoil-distance method. The large collectivity observed for the 4(+) -> 2(+) transition suggests a prolate character of the excited states. The reduced collectivity previously reported for the 2(+) -> 0(+) transition was confirmed. The irregular behavior of collectivity points to the occurrence of a rapid oblate-prolate shape transition in Kr-72, providing stringent tests for advanced theories to describe the shape coexistence and its evolution.
