Proton emission from Pm 125 could be observed

We perform a feasibility study for the search of proton decay from Pm, the last element without an isotope found, that decays by proton emission in the region of charges between 50 and 83. The behaviors of the half-lives for decay from the ground and possible isomeric states of 125Pm are discussed as a function of deformation, spin of the decaying state, and energy of the emitted proton, indicating the most probable regions of energy where proton radioactivity might be detected. We find that within our predictions, proton decay from 125Pm could be measurable.
