Abstract
We discuss the relation between two standard approaches applied to dif fusion in the presence of anisotropic scattering. The diffusion consta nt obtained from the Boltzmann equation is different from that obtaine d by a random walk model with fixed step length. By varying the step l ength according to a Lambert-Beer law we recover the Boltzmann result.
