Decay rates of spherical and deformed proton emitters

Abstract

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 \AA{}berg et al. in the spherical case.
