Nanosecond isomers in near-spherical 142,143Pm
Abstract
In-beam measurements of nanosecond lifetimes have been undertaken for some of the excited states in near-spherical nuclei 142,143Pm using the pulsed-beam γ coincidence technique and the generalized centroid-shift method of analysis. The 133Cs(13C,xn) reaction with a 60 MeV pulsed beam of 13C was used to populate the excited states in the respective nuclei. The measured mean lifetimes have been compared with corresponding single-particle estimates.
