The decay scheme of Se⁷⁵ Schneider, Harvey Roy
Excited levels of As⁷⁵ were investigated by studying the decay of Se⁷⁵. Scintillation detection techniques were employed to measure, the relative gamma ray intensities, gamma-gamma coincidences, and conversion electron-gamma coincidences. A decay scheme with five excited As⁷⁵ levels at 200, 265, 280, 305 and 402 kev. is proposed. Multipolarities are assigned to the transitions between these levels on the basis of conversion coefficients, determined from previously measured conversion intensities.
