Additional information has also been extracted from the reaction Sm-144(S-32, 2pn) Os-173. Four main sequencies have been identifie as the two signature branches of the bands built on the [642]5/2+ and [523]5/2- Nilsson states. The band features have been analysed within the framework of the cranked shell model. The positive-parity band provides evidence for a v(i13/2)2 crossing at low frequency and a pi(h11/2)2 and/or pi(h9/2)2 crossing at higher frequency. In the negative-parity band the upbend starts at relatively low frequency indicating, presumably, an early v(i13/2)2 alignment. There is evidence for another two band crossings possibly due to v(i13/2)2 alignment of a different configuration and a high frequency proton alignment as in the positive-parity band. B(M1)/B(E2) ratios have also been extracted in both bands to deduce further information on the detailed structure of the bands.http://hdl.handle.net/123456789/105711223ISI:A1991FH484000122050375-9474526engELSEVIER SCIENCE BVNuclear Physics, Section AISOTOPESNUCLEINEUTRON-DEFICIENTSPECTROSCOPYALIGNMENTDECAYYRAST BANDSTRANSITIONSSHAPE COEXISTENCENuclear reactionsStudy of high spins in 173OsjournalArticle1991Δημοσίευση σε περιοδικόPublication in journalΠυρηνική φυσικήNuclear Physicsisi - Physics, Nuclear includes resources on the study of nuclear structure, decay, radioactivity, reactions, and scattering.
