【 摘 要 】

Rotational bands in (sup 175)Lu have been extended through investigation with the (n,n(prime)(gamma)) reaction. Spallation neutrons bombarded Lu samples, and the resulting (gamma) rays were detected in a large-scale Compton-suppressed Ge detector array. Prompt- and delayed-(gamma)(gamma) coincidences have been used to extend most of the existing known bands, and to tentatively assign a new band, based on the 7/2(sup -)(523) configuration, from its band head to spin 13/2. The 3-quasiparticle K(sup (pi)) = 19/2(sup +) isomer is confirmed and its half life determined to be 984 (+-) 13(stat.) (+-) 30(sys.) (micro)s, in agreement with previous results.
