Abstract:The observation of a weak proton-emission branch in the decay of the 3174-keV 53mCo isomeric state marked the discovery of proton radioactivity in atomic nuclei in 1970. Here we show, based on the partial half-lives and the decay energies of the possible proton-emission branches, that the exceptionally high angular momentum barriers, $${{{{{{\mathcal{l}}}}}}}_{{{{{{\rm{p}}}}}}}=9$$
