Abstract

The isotope separator facility OASIS, on-line at the Lawrence Berkeley Laboratory Super-HILAC, was used to investigate proton-rich rare earth nuclei. Single-particle states near the 82-neutron shell were delineated, numerous new isotopes, isomers and β-delayed proton emitters were discovered and the α-decay properties of some nuclides with N ≥ 84 were re-examined. In this contribution the experimental program is summarized briefly, the excitation energies of the s 1 2 and h 11 2 proton states in this mass region are discussed, and results on the β-delayed-proton spectra of 145Dy and 147Er are presented.
