| Abstract: | We use Boltzmann's transport equation to calculate the 3D incoherent Landauer equation for neutrons and photons diffusing in a slab of amorphous material. We use the P-1 approximation to calculate the multiple-scattering transmission coefficient as a function of the diffusion coefficient. The 3D transmission coefficient obtained is smaller than the 1D case. The P-1 result, valid only for thick slabs, is proved to be an excellent approximation to the exact solution.
