摘要: Abstract The gamma rays in Se81 and Br81 following the decay of Se81m were studied with a magnetic spectrograph. Three internal conversion lines observed these measurements. Gamma-ray spectra taken NaI(Tl) detector indicated transition at 30 keV addition to previously reported rays. Measurements made coincidence five energy regions. results indicate levels 280 keV, 560 832 agree main features scheme proposed by Krause et al. Beta-gamma measurements showed that level is different than 550 which excited (p, γ) (γ, γ′) reactions. Intensities transitions computed.
