Phys. Rev. C 69, 034316 (2004) [10 pages]High-spin study of rotational structures in 72BrReceived 20 October 2003; published 15 March 2004 High-spin states in 3572Br37 were studied using the 40Ca(36Ar,3pn) reaction. The existing level scheme has been significantly modified and extended. Evidence has been found for a spin reassignment of −1ℏ to the previously observed negative-parity band, which carries implications for the interpretation of a signature inversion in this structure. One signature of the previously assigned positive-parity band is interpreted as negative parity and has been extended to Iπ=(22−) and its signature partner has been observed up to Iπ=(19−) for the first time. The remaining positive-parity band has been extended to Iπ=(29+). A sequence of states observed to Iπ=(22+) may be the signature partner of this structure. Configurations have been assigned to each of these three structures through comparisons to cranked Nilsson-Strutinsky calculations. © 2004 The American Physical Society URL:
