Table of three-quasiparticle rotational bands in deformed nuclei, 153 ⩽ A ⩽ 187

Abstract

The experimentally observed level structures based on three-quasiparticle (3qp) states are classified according to their intrinsic structures, and other properties are deduced from measurements such as B( M1)/ B( E2) ratios, | g K − g R| values, lifetimes, etc. The present table lists data for a total of 168 such structures which have been extracted from the literature for 55 nuclides in the mass region A = 153–187 ( Z = 63–78, N = 88–112), with the majority of these bands in the A = 180 region (28 bands in seven Re isotopes alone). Nuclear models used for the interpretation of 3qp structures, generalization of the Gallagher–Moszkowski (GM) rules to 3qp states, and high-spin features such as t-bands, high- K isomers, signature splitting, signature inversion, alignment, etc., are discussed briefly. The literature cutoff date for extraction of data for known 3qp structures is July 15, 2005.
