The lifetimes of the y rays in the collective rotational bands observed in the y-ray continuum at very high spin in 152 Dy are shown to be less than 100 fs for energies above 0.90 ± 0.05 MeV. The corresponding B(E2) values are very enhanced and provide definite evidence that the rotational bands are associated with a superdeformed prolate structure in 152 Dy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
