Neutron Slowing down and Transport in an Infinite Medium: 2, The Scalar Flux at Large Distances/Small Lethargies

摘要

A companion paper has presented a Generalized Age-Theory expression for the scalar flux PSI sub 0 /sup G/(x,u) due to a plane isotropic source emitting neutrons in an infinite medium with cross sections that are constant in energy. The range of validity for this Generalized Age-Theory expression has also been determined as p = x/(2u) less than or equal to R(A), where R(A), the range of validity, is a function of the scatterer's mass. The purpose of this paper is to present the expression for the scalar flux Psi sub 0 /sup G/(x,u) in the complementary region in phase-space, i.e., where p > R. (ERA citation 12:048975)
