Etude du schéma de désintégration de 76As

Resume The decay of 76 As was investigated with a coaxial Ge(Li) detector. Energies and intensities of 42 γ-rays were measured, 19 of them were reported for the first time, γ-γ coincidence experiments were performed with a Ge(Li) NaI(Tl) spectrometer. A level scheme of 76 Se is deduced which interprets almost all the transitions. Three new levels are suggested at 2025.2, 2170.5 and 2514.4 keV.
