Abstract The decay of theβ +-fed isobaric analog state by one- and two-proton emission is calculated in the formalism of compound-nucleus decay. Support is given to the uncorrelated character of the emitted protons in theβ2p process. The ratio ofβ2p toβp probabilities is obtained for the isotopes predicted to beβ2p emitters up to Z=30, i.e.22Al,22,23Si,26P,27S,31Ar,35Ca,39Ti,43Cr,46Mn,46,47Fe,49–51Ni, and55Zn.
