SPECTROSCOPY OF PROTON-RICH NUCLEI IN THE RARE-EARTH REGION

[摘要] 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 32-neutron shell were delineated, numerous new isotopes, isomers and beta-delayed proton emitters were discovered and the alpha-decay properties of some nuclides with N greater-than-or-equal-to 84 were re-examined. In this contribution the experimental program is summarized briefly, the excitation energies of the S1/2 and h11/2 proton states in this mass region are discussed, and results on the beta-delayed-proton spectra of 145Dy and 147Er are presented.
