Decay of As⁷⁹

Abstract

As 79 was produced by a strong bremsstrahlung from a linear electron accelerator. It was separated chemically from SeO 2 irradiated by the bremsstrahlung. The decay of As 79 was studied with the aid of scintillation spectrometers. From the information of the gamma and beta spectra and of the coincidence measurements, the decay scheme of As 79 was proposed.
