摘要：

The β+ decay of 75Br to levels of 75Se has been investigated with the use of Ge(Li), NaI(Tl) gamma-ray detectors and Si(Li) positron detector. Seven gamma rays and five positron branches have been observed. On the basis of various gamma-gamma, gamma-beta coincidences and positron intensity measurements, a decay scheme is proposed with levels of 75Se located at 111.8, 286.5, 427.5, 579.5, 663.8 and 859.1 keV. The half-life of the 286.5 keV level has been measured to be τ 1 2 = 1.23 ± 0.15 ns. The properties of the levels are discussed. © 1969.
