Monoenergetic Neutral Particle Transport in Semi-Infinite Media

Abstract

A large class of half-space transport problems for neutral particles is considered including single and adjacent half-space geometries. Localized and distributed sources emitting particles either in a particular direction, isotropically or with a given angular distribution are considered. All solutions are based on the solution to the well-known albedo problem. A numerical Laplace transform inversion is used to generate highly accurate benchmark solutions which can be used to assess the error incurred by numerical transport algorithms.
