“…The errors vary between 10 and 30% depending on the line strength and the complexity of the spectrum. The lowest ~-ray energy observed in this experiment was a 22.2 keV transition in coincidence with the ~32.4 keV 7-ray belonging to VSBr [10]. In column 4 the ratios of the y-ray intensities determined in the (d, 2n) reaction at bombarding energies of 12 and 13.5 MeV are presented Angular distribution coefficients according to the formula W(O)=Iy(l +A2P2(cosO)+A,~P4(cosO)) as determined in the (~, p2n) reaction at 32 MeV.…”

An in-beam study of 74Br has been carried out using y-ray spectroscopy in connection with the reactions (3He, p2n) and (d, 2n) on 74Se targets. Separate level schemes on top of the two/?-decaying isomers of 74Br are proposed. Two cascades connecting highspin states are assigned to populate the U =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 of 74Br is tentatively assigned as U = (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 (7~g9/2, vg9/2) and (=P3/z, Vgg/2). As a by-product, a cascade of four transitions has been observed during the 3He bombardment of V4Se and tentatively assigned to negative-parity states in 75Kr.

“…In the spectra of 7-rays emitted by the 74Se target during beam-off time (4 ms) of the pulsed 3He beam (duty cycle 80%) the known 7-rays from the decay [10] of the 75Kr ground state have clearly been observed. The relative excitation function for this activity was determined for the bombarding energies of 28 and 32 MeV.…”
