Excited quasiparticle states of odd-mass deformed nuclei in the transplutonium elements

In this paper the author summarizes experimental evidence from the published literature for excited single-particle configurations in the actinide-element deformed nuclei. Experimental data are compared for the levels of 249Bk and 245Cm with two recent theoretical treatments, one calculation of pure single-particle levels and another in which interactions between single-particle and collective motions are included. In the latter half of the paper new information is presented on 249Bk levels from nuclear spectroscopic measurements of 253Es alpha decay and 249Cm beta decay performed at Lawrence Livermore Laboratory and Laurence Berkeley Laboratory.
