Das Gammaspektrum des34Se81

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