decay from the lowest T=2 state in $^{22}Mg$ - the isobaric analogue state (IAS) of the $^{22}Al$ ground state - to the ground and the first excited states in $^{21}Na$. This IAS is measured to be at an excitation energy of 13650 $\pm$ 15 keV and is fed by a superallowed $\beta^+$ decay. Based on the T=2 isospin multiplet, a $I^{\pi} = 4^+$ was assigned to the $^{22}Al$ ground state. A rough half-life value of $70^{+50} _{-35} ms$ was also determined. Due to the technique used, no absolute branching ratios could be determined. In another study of this nucleus, the first observation of the exotic $\beta$-2p decay was published by Cable [*et al.*]{} [@cable83]. Two $\beta$-delayed 2p decay branches were observed. From energy considerations, these two branches were attributed to transitions from the IAS in $^{22}Mg$ to the first excited state and the ground state of $^{20}Ne$. In a recent experiment performed by Blank [*et al.*]{} [@blank; @czajkowski], the $\beta$-$\alpha$ decay of this nucleus was observed for the first time using a technique based on the implantation of $^{22}Al$ into a silicon detector and into a micro-strip gas counter. A half-life of $T_{1/2} = 59 \pm 3~ms$ was measured. A
