摘要：

High-spin states in Br-72(35)37 were studied using the Ca-40(Ar-36,3pn) reaction. The existing level scheme has been significantly modified and extended. Evidence has been found for a spin reassignment of -1h 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 I-pi=(22(-)) and its signature partner has been observed up to I-pi=(19(-)) for the first time. The remaining positive-parity band has been extended to I-pi=(29(+)). A sequence of states observed to I-pi=(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.
