Abstract

Decay studies on rare earth nuclei around the proton drip line have been performed by means of the Recoil Mass Spectrometer at the Holifield Radioactive Ion Beam Facility in Oak Ridge. The proton emission from the odd-odd N=77 isotone ¹⁴⁶Tm was reinvestigated, resulting in the assignment of the 1.01 MeV proton line to the decay of a short-lived ¹⁴⁶Tm state. A new proton radioactivity of ¹⁴⁴Tm was identified. The decays of isomeric levels in the N=77 isotones, ¹⁴⁰Eu, ¹⁴²Tb and ¹⁴⁴Ho were remeasured using γ and electron detectors. The analysis of the structure of studied nuclei, which accounts for the coupling between the protons and neutrons and for core excitations, is presented.
