First identification of high-spin states in $^{152}$Pr

ORAL

Abstract

The odd-odd neutron-rich nucleus $^{152}$Pr has been studied from the spontaneous fission of $^{252}$Cf with the Gammasphere detector array at Lawrence Berkeley National Laboratory. A high-spin level scheme of $^{152}$Pr has been established for the first time. Angular correlation and internal conversion coefficient measurements are used to determine level spins and parities in the yrast band of $^{152}$Pr relative to the band head. The possible configurations of the band head have been discussed based on systematics and total Routhian surface calculations. The results will be presented.
