Abstract

Excited states in the proton-unbound nucleus 151Lu have been established using γ -ray coincidence techniques. The lifetime of the first excited state above the proton-emitting ground state has been measured using the recoil-distance Doppler-shift method combined with recoil-decay tagging. The experimental
level scheme and extracted lifetime have been compared with state-of-the-art theoretical calculations based upon a non-adiabatic deformed Woods–Saxon potential. This comparison suggests that the protonemitting ground state in 151Lu is mildly oblate with a deformation β = −0.11+0.02 −0.05 and represents the
best evidence to date for proton emission from an oblate nucleus
