Abstract The decay of Se81 (18 min) produced by neutron bombardement of natural Se and 98% enriched Se81 has been studied with the aid of scintillation-spectrometers. Gamma-rays have been observed and could be identified as belonging to the decay of Se81, revealing three excited levels in Br31 at (282±3) keV, (565±6) keV and (820±10) keV. The branching ratios of the beta-components are 98,7% leading to the ground state and (0,06±0,03)%, (0,85±0,20)% and (0,40±0,10)% leading to the excited states, respectively. The 565 keV-level decays to the ground state directly or by a cascade-transition with nearly equal intensities, the 820 keV-level mainly by a direct transition.
