$15^*$ corresponds to a $\beta$-$\alpha$ decay to the $^{18}Ne$ first excited state. In these two cases, the $\beta$-2p and $\beta$-$\alpha$ peaks are superimposed on proton transitions. The only way to distinguish between these transitions and the proton emission, to get the branching ratios, is to use the coincidences with $\gamma$-rays.\
    The peak $23^{**}$ with $E=6.085 \pm 0.008$ MeV is compatible with the $\beta$-2p decay measured by Cable [*et al.*]{} [@cable83] to the $^{20}Ne$ ground state. For the $\beta$-2p transitions, the proton detection efficiency was taken at half of the transition energy.\
