Title: Nuclear data sheets for {sup 165}Lu

Abstract

The experimental nuclear structure data for {sup 165}Lu have been compiled and evaluated. Extensive revisions to all the data sets for this nuclide have been made, based on the new high-spin study of 1995Sc39. From the interconnections of different rotational bands in 1995Sc39, the assignment of the ground state and its spin have been revised. There does not seem any evidence to support isomerism in {sup 165}Lu as proposed earlier in the 1987 Nuclear Data Sheets (and the 1992 update) of A=165, the Wall Chart of Nuclides and by 1997Au04. The assignment of 1/2+ to the ground state is also supported by the recent (1998Ge13) laser-spectroscopic measurements of hyperfine structure. A superdeformed (triaxial) structure is reported by 1995Sc39. This revision supersedes earlier {sup 165}Lu data contained in the A-165 update published by L.K. Peker. Nuclear Data Sheets 65, 439 (1992) with literature coverage up to Nov. 1, 1990. The transitions connecting the low lying states to the ground state are expected to be in the low-energy region of 5 to 24 keV for which experiments to measure conversion electrons are needed.
