Abstract
Aspects of transport in a highly multiple-scattering environment are investigated by examining random walkers moving in media having anisotropic angular scattering cross sections (turn-angle distributions). A general expression is obtained for the mean square displacement 〈x2〉 of a random walker executing ann-step walk in an infinite homogeneous material, and results are used to predict scaling relations for the probabilityγ(ρ) that a walker returns to the planar surface of a semi-infinite medium at a distanceρ from the point of its insertion.
