Thermal spike analysis of interface mixing induced by swift heavy ions was discussed. Diffusion in the ion-induced melt was assumed and an expression for the variation of the mixing rate k with the electronic stopping power Se was derived. Average diffusion coefficients in the spike, Dd≈0.053, 0.03, and 0.004 cm2/s were obtained for Zn, Ni, and Cu ions, respectively.
