Rotational structure of highly deformed /sup 99/Y: Decay of /sup 99/Sr
Journal Article
·
· Phys. Rev. C; (United States)
The level structure of the N = 60 isotone /sup 99/Y has been studied via the decay of /sup 99/Sr. ..gamma.. singles and ..gamma..-..gamma.. coincidence measurements have resulted in 71 ..gamma.. transitions placed in a decay scheme with 26 levels. ..gamma..-ray multiscaling measurements give a /sup 99/Sr half-life of 270 +- 10 ms. Five rotational bands, including the previously identified K = (5/2) ground-state band, have been identified in /sup 99/Y. Nilsson orbitals, with bandhead energies in keV in parentheses, associated with these five bands are (5/2)(422) (0), (5/2)(303) (487), (3/2)(301) (536), (1/2) (431) (1011), and (3/2)(431) (1119). The rotational features are consistent with an axially symmetric deformation in the range 0.3 to 0.4. The characteristics of these bands and their associated ..gamma..-ray transitions are discussed.
