Abstract

Recent proton radioactivity studies at the Holifield Radioactive Ion Beam Facility at Oak Ridge are presented. The experiments were performed by means of a Recoil Mass Separator (RMS) and digital processing of its detector signals. Observation of fine structure in proton emission from the activities : 145Tm (T1/2 ≈ 3/is) and 146m,gs,Tm (T1/2 ≈ 200 ms and 100 ms, respectively) is reported. The structure of the proton emitting states is analyzed in terms of a spherical approach. The properties of daughter states, a 2+ state in 144Er and the s1/2 and h1/2 neutron levels in 145Er, are deduced.
