Gamma rays following the decay of 75Se

Abstract

The gamma-ray spectrum of 75Se has been studied using lithium-drifted detectors. Seven new transitions have been observed for the first time. The energies in keV and the relative intensities (indicated in parentheses) of the new gamma rays observed are 335.14(0.18), 415.10 (2.76 × 10 −2), 485.58(3.68 × 10 −3), 528.55(1.46 × 10 −2), 535.79(9.34 × 10 −3), 543.03(1.40 × 10 −2) and 556.55(3.04 × 10 −3). The energies and relative intensities of the other gamma rays in the decay are also measured.
