Structural behavior of Dy-157,Dy-158,Dy-159 in the I=30-50h spin regime
(2005) In Physical Review C: covering nuclear physics 72. p.1-064307- Abstract
- Significant extensions to the high-spin excitation spectrum of the N = 91, 92, 93 isotopes Dy-157,Dy-158,Dy-159 have been achieved using the high-efficiency gamma-ray spectrometers Euroball and Gammasphere. These nuclei were populated via weak 3n or alpha xn exit channels in fusion evaporation reactions. In Dy-157, the yrast band has been extended to I-pi = (2)/(101+) (tentatively to (2)/(105+)) with four sideband structures (two of which are new) observed in the 35-50h spin range. In Dy-158, three bands have been extended to 42(+)(44(+)),40(-), and 41(-)(43(-)), whereas in Dy-159 the yrast band is observed to (2)/(81+) ((2)/(85+)). The high-spin behavior and band crossing systematics of the Dy isotopes and of the neighboring N = 91, 92,... (More)

The high-spin behavior and band crossing systematics of the Dy isotopes and of the neighboring N = 91, 92, and 93 isotones are discussed in terms of rotational alignments and shape transitions. Cranked Nilsson-Strutinsky calculations without pairing have been performed for detailed comparisons with the very high-spin states observed in Dy-157. (Less)
