Abstract

Beta-delayed proton radioactivity has been observed for the Tz = −52 isotope 31Ar which has been produced by projectile fragmentation of 36Ar at 85 MeV/u. The 31Ar measured half-life is T12 = 15 ± 3 ms, in good agreement with shell-model calculations; spectra of beta-delayed protons have been obtained. No evidence was found for direct two-proton-decay of 31Ar.
