A Search for Neutron Single-Particle States Populated Via Proton Emission from [sup146]Tm.

We studied the proton emission from [sup146][sub69]Tm[sub77] and observed three new transitions. New transition at 0.89 and 0.93 MeV have half-lives similar to that of the previously observed transition at 1.19 MeV, while a new transition at 1.02 MeV has a half-life similar to that of the previously observed transition at 1.12 MeV. These new transitions indicate the population of excited neutron single-particle states in [sup145][sub68]Er[sub77] [ABSTRACT FROM AUTHOR]
