Abstract

States in 130Ce have been studied using 16O induced reactions on 117Sn and 118Sn targets. Mean lifetimes have been measured for the yrast states up to Jπ = 22+ using both the Doppler shift attenuation and recoil distance methods. Magnetic dipole transition rates have been deduced from branching ratio measurements within a band based on an isomeric state at 2454 keV. Electric quadrupole transition rates have been determined from mean lifetime measurements for states in the yrast band up to Jπ = 22+. Both sets of results show an unexpected behaviour.
