Gamma transitions following the decay of 75Se have been studied using a Ge(Li) detector and a NaI(Tl)–NaI(Tl) sum-coincidence spectrometer, used in conjunction with a slow-fast coincidence circuit. Two new gamma rays of energy 373.5 and 556.4 keV have been observed and confirmed in the level scheme of 75As. Ambiguous gamma transitions of 249.2, 468.6, 542.2, and 821.6 keV energies have also been confirmed. No evidence was found for the existence of 269.0, 293.0, and 308.0 keV transitions. The accurate intensities for various transitions have been determined.
