High-spin positive-parity states in {sup 72}Br have been studied using the {sup 16}O+{sup 58}Ni reaction. The {pi}g{sub 9/2}{nu}g{sub 9/2} decoupled band in {sup 72}Br has been observed up to {approximately}10 MeV excitation energy and the expected odd-even staggering has been delineated. A larger signature splitting is observed for this band in {sup 72}Br than in the same collective structures in the heavier {sup 74,76,78}Br. No signature inversion at low spin is observed for this band in {sup 72}Br, in contrast to the heavier isotopes, {sup 74,76,78}Br, in which signature inversion is observed below {approximately}10{h_bar}. The observations are in general agreement with theoretical models in this mass region which predict no signature inversion for nuclei with less than 39 protons and neutrons. {copyright} {ital 1999} {ital The American Physical Society}
