High-K structures in {sup 180}W and {sup 181}W

Abstract

In each of the prolate-deformed isotopes {sup 180}W and {sup 181}W, a very high-K non-collective state has been found which decays directly into the corresponding collective ground-state rotational band. There is complete breakdown of the K-selection rule, in contrast to the partial breakdown observed recently in {sup 174}Hf and {sup 182}Os. Nevertheless, the non-collective states themselves retain characteristics associated with a prolate axially symmetric shape, implying that K is still a useful quantum number. (author). 17 refs., 2 figs.
