Abstract

On-line mass separation and K x-ray coincidences were used to identify the decays of Er145 and Ho145. Only -delayed proton emission was observed for Er145 (T1/2=0.9±0.3 s), and a total of 16 -ray transitions were assigned to the decay of Ho145 (T1/2=2.4±0.1 s). A Ho145 decay scheme was constructed which incorporates 13 -ray transitions and 10 excited levels in Dy145 and establishes the h11/2 isomeric level at Ex=118.2 keV. The low-lying neutron-hole structure in Dy145 is compared to level systematics in even-Z nuclei with N=77, 79, and 81.
