On the zero-energy moments of the distribution of fast atoms and cascades

Abstract

The slowing down of neutrons in capture-free hydrogen is not only a classic problem in transport theory but is a paradigm for several problems in the interaction of energetic ions with matter. Here we are concerned primarily with the distribution of stopped particles. We describe a novel expansion for the transport equation which which gives extremely accurate results for the moments of the distribution and which proves an earlier conjecture made by E.M. Baroody. We discuss additional applications of the expansion, which appears to be an improved "straight-ahead" approximation.
