Decay Study of Bromine-75

The radioactive decay of bromine-75 has been studied with a 16-cc Ge(Li) detector and a standard scintillation spectrometer. The bromine isotope was produced with carbon-12 ions (3.9 MeV/nucleon) on natural copper targets. The following $\gamma$ rays, decaying with a half-life of 95.5±1.5 min, have been found: 110±1, 140±1, 286±1, 378±1, 426±1, 430±1, 569±1, 606±1, 654±1, 728±1, 788±1, 900±1, 940±1, 948±1, and 1233±2 keV. Coincidence measurements were performed, and a tentative decay scheme for bromine-75 is given.
