NEUTRON DIFFUSION AT LARGE DISTANCES FROM THE SOURCE

Abstract

Bethe's theory of diffusion of neutrons from an isotropic monoenergetic source in an infinite homogeneous medium (AECD 2105) is generalized to include a mixed homogeneous medium and constant capture. The theory deals with neutron densities at large distances from the source and covers the gap between age theory and the asymptotic theory of Wick. All scattering and capture cross sections were assumed independent of neutron energy, and only elastic collisions were considered.
