Abstract
The atomic diffusion coefficient of channeled particles has been constructed within the Doyle–Turner approximation of the potential of an isolated atom. It is shown that the atomic diffusion coefficient seeks its minimum value in the region of the maximum nuclear density of the atomic chain where the Kitagawa–Ohtsuki diffusion coefficient reaches its maximum value. Atomic diffusion coefficients have been modeled with the TROPICS software that was upgraded for calculations on heterogeneous structures.
