An in-beam study of74Br has been carried out using ?-ray spectroscopy in connection with the reactions (3He,p2in) and (d,2n) on74Se targets. Separate level schemes on top of the two ß-decaying isomers of74Br are proposed. Two cascades connecting highspin states are assigned to populate theIp=4(+) isomer. In this level scheme, the excited states at 72.1, 188.3 and 472.0 keV are found to have half-lives of 13.3, 0.7 and 0.7 ns, respectively. The low-spin isomer of74Br is tentatively assigned asIp=(0-). This state is populated by two other cascades. For the low-spin levels two-particle configurations of proton and neutron Nilsson orbitals are proposed. The high-spin states are tentatively interpreted as arising from the configurations (pg9/2,?g9/2) and (pg3/2,?g9/2). As a by-product, a cascade of four transitions has been observed during the3He bombardment of74Se and tentatively assigned to negative-parity states in75Kr. |
