High-spin structure of \(N\simeq Z\) nuclei around the A = 72 region

High-spin states have been studied in 72Kr and 72Br using the 40 Ca + 40 Ca and 36 Ar + 40 Ca reactions at 164 and 145 MeV, respectively. The properties and configurations of the high-spin bands observed have been interpreted using unpaired cranked Nilsson-Strutinsky (CNS), and for 72Kr, paired cranked relativistic Hartree-Bogoliubov (CRHB) calculations. In 72Kr a new band has been identified that has the properties expected for the doubly aligned S-band configuration. In 72Br the previously known bands have been extended to higher spin. This has lead to a re-interpretation of the configurations.
