Abstract

Position-sensitive detectors have been used to measure the angular correlation of the two protons de-exciting the

4^{+}

,

T = 2

isobaric analog state in

{}^{22}{Mg}

fed in the

β^{+}

decay of

{}^{22}{Al}

. The observed isotropy indicates a predominantly sequential decay mechanism. However, a 15% admixture of correlated di-proton (

{}^{2}{He}

) emission cannot be excluded.
