Steady-state point-defect diffusion profiles in solids during irradiation

Abstract

Abstract The steady-state distribution of mobile point defects in a monatomic solid under irradiation has been calculated for a semi-infinite solid and for a foil. The calculation was performed for defect annihilation by mutual recombination, at internal sinks, and by diffusion to the surface. Simple approximations, accurate to within 5%, have been developed for the analytical solutions to the differential rate equations.
