First identification of high-spin states in the odd-odd neutron-rich nucleus152Pr

Abstract

The odd-odd neutron-rich nucleus ${}^{152}$Pr has been studied from the spontaneous fission of ${}^{252}$Cf with Gammasphere. 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 the transition multipolarities. The possible configurations of the bandhead have been discussed based on systematics and total Routhian surface calculations.
