Abstract
Fusion-evaporation reactions induced by a beam of 25-50 MeV on an isotopically enriched target have been used to populate high-spin yrast levels in , , and . Measurements consisted of - ray excitation functions, angular distributions, coincidences, and recoil-distance and Doppler shift lifetime measurements, from which were deduced the energy levels, -ray branching ratios, most probable spin-parity assignments, and level lifetimes.
