摘要：

A positive parity sequence of Delta I =2 gamma transitions has been identified above I-pi = 9/2(+) state (E-x = 2019 keV) in Sb-115 through in-beam gamma ray spectroscopic technique. Rotational features of this sequence are found similar to a low-K decoupled band. Observation of this newly identified low-K decoupled band, along with the earlier reported strongly coupled high-K band in this nucleus, provides the first experimental evidence for prolate-oblate shape coexistence associated with g(9/2) proton-hole configuration around Z = 50 shell closure. Experimental results are reproduced reasonably well in the frameworks of the projected shell model and the total Routhian surface calculations.
