Maximum entropy for half-space energy albedo

Abstract

The maximum entropy method is used to find the energy albedo for half-space, i.e., the classical albedo problem but extended to include energy dependence. The slowing-down kernel is described by elastic scattering and various model representations for dealing with anisotropic scattering. The energy albedo for different values of secondary particles per collisionC is calculated and compared with exact and variational values given by Williams and Padé's approximant given by Machaliet al. (1981). Also the energy albedo for different mass-ratios is found and compared with Williams and Padé's results.
