Diffusion approximation revisited

Journal of the Optical Society of America A, 2009
We study the diffusion approximation (DA) to the radiative transport equation (RTE) in infinite homogeneous space. Different definitions of the reduced intensity I(r) that satisfy a simplified RTE (without accounting for scattering) and that are often used in the derivation of the DA are examined. By comparing the results of the DA with exact solutions

Diffusion approximations to cascade mixing

Radiation Effects, 1979
Abstract In two recent studies1, 2 of cascade mixing, the process in which energetic ion bombardment can redistribute the atomic components of a multielemental target via recoil processes, a diffusion approximation has been assumed, apparently with signif-icantly different results2. It is the purpose of this communication to reveal the close similarity
