| 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 of the two existing treatments and to indicate some important modifications and extensions. |
