In a recent work we derived new diffusion approximations for the collision density and energy density about an isotropic point source in an infinite isotropically-scattering medium in arbitrary-dimensional space with general free-path distribution. In this brief followup we prove several conjectures from our previous paper, show new results for the energy density about the point source, and provide more general derivations that avoid the necessity for any Fourier transforms.
