Nuclear spectroscopy in the rare earth region near the proton drip line
- Oak Ridge National Lab., TN (USA)
We have used the isotope separator facility OASIS, on-line at the Lawrence Berkeley Laboratory SuperHILAC, to investigate rare earth nuclei close to the proton drip line. Single-particle states near the 82-neutron shell have been examined and their excitation energies determined. Numerous new isotopes, isomers, and {beta}-delayed proton emitters have been discovered. In addition, the {alpha}-decay properties of nuclides with N {ge} 84 have been reexamined; this has led to the discovery of several previously unobserved {alpha} transitions. The overall experimental program is summarized and some recently obtained results on {sup 145}Dy, {sup 147}Er, {sup 147}Tm, {sup 153}Lu, {sup 155}Lu, and {sup 157}Lu are discussed. 20 refs., 11 figs., 11 tabs.
