Solutions to inverse problems for the Boltzmann-Fokker-Planck Equation

Abstract
Equations are developed with which to evaluate the coefficients used in the one-speed Boltzmann-Fokker-Planck transport equation for strongly anisotropic scattering of photons or neutrons. The inverse equations, which are derived for a homogeneous slab target, require only measurements outside the medium. One set of equations is useful when the external illumination is nonuniformly incident over the surface, and the other set is valid for a uniform illumination of the target.
