Using Green’s function techniques, we derive expressions for the width of a proton decaying state in spherical and deformed nuclei. We show that the proton decay widths calculated by the “exact” expressions of Maglione et al. are equivalent to the distorted wave expressions of Bugrov et al., and that of Åberg et al. in the spherical case.
