Abstract
We numerically solve a diffusion-type equation for the accumulated int erdiffusion coefficient in an interacting system (nonideal ion-exchang e reaction) by using a modified Crank-Nicolson algorithm. We obtain ex act and approximate index profiles in such a way that bump effects fou nd in experimental ionic concentrations in glass are explained as a re sult of cation-cation interactions.
