The partial proton emission half-life for 53mCo unstable isomer is re-examined in the framework of a semiempirical model based on tunneling through a Coulomb-plus-centrifugal-plus-overlapping potential barrier within the spherical nucleus approximation. It is shown that the known measured half-life value of 17s is compatible with a large prolate shape for 53mCo proton emitter and a high angular momentum ℓ = 11 assigned to the proton transition to the ground state of 52Fe .
