Effects induced by a nuclear stratosphere upon statistical particle emission processes are discussed. The calculations are based on the compound nucleus emission model and they include the formation of a nuclear stratosphere. This degree of freedom is accounted for by effective potentials for particle emission channels. The radial dependence of these potentials is adjusted in order to reproduce the temperature-dependent shape evolution of nuclear radial distribution functions. Results are discussed for ${}_{}{}^1{}_{}{}^{}\mathrm{H}$${/}^4$He emission rates from the compound nucleus ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$.
