of counts in the unconditioned proton spectrum after subtraction of the $\beta$ contribution.\
    The ratio $R_2=53.5\%$ is determined from a fit of a relatively isolated proton peak in the conditioned proton spectrum (E5 &gt;0). We have chosen the peak labelled 11 at E=2.583 MeV. The low energy part of the peak was fitted by a Gaussian while the total peak was fitted by a Gaussian added to an exponential function for the high-energy tail.

    Each proton peak in the conditioned spectrum was fitted by a Gaussian, the area obtained was divided by $R_1$ and $R_2$ and by the number of $^{22}Al$ implanted. The branching ratios obtained were corrected for the proton detection efficiency.

    The proton peak energies and their branching ratios are given in table \[tab:pro22al\] and compared with previous measurements of Blank [*et al.*]{} [@blank]. We observe an overall agreement but many new or better defined peaks above the proton threshold in $^{22}Mg$ were measured.\
    The branching ratios of the peaks $15^*$,$17^{**}$ and $23^{**}$ have not been corrected for proton detection efficiency as the other peaks because, as it will be shown later, peak $17^{**}$ is assigned to a $\beta$-2p transition to the $^{20}Ne$ first excited state and peak
