Abstract

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 -1ℏh 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 ^π=(22^-) and its signature partner has been observed up to I^π = (19^-) for the first time. The remaining positive-parity band has been extended to I^π=(29⁺). A sequence of states observed to I^π=(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.
