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