Phys. Rev. C 45, 69–79 (1992)Decay modes of 31Ar and first observation of β-delayed three-proton radioactivityReceived 10 June 1991; published in the issue dated January 1992 The different β-delayed particle-decay modes of 31Ar are investigated by means of a new silicon-detector telescope. Identification of β-delayed two-proton decay, and β-delayed three-proton decay observed for the first time, is made possible by Monte Carlo simulations of the detector response. Other β-delayed single-proton branches are also investigated, and none of the energetically allowed β-α and β-pα decay modes are found. Finally, the results of this experiment are compared to shell-model calculations. © 1992 The American Physical Society URL:
