On Asymptotic Formulae of the Theory of Radiation Transfer in a Sphere and a Spherical Envelope
Abstract
Integral constraints for the radiation intensities in homogeneous, absorbing and anisotropically scattering media with radial symmetry are obtained. Asymptotic formulae for the radiation intensities in the outer layers of a sphere of large optical radius and an optically thick spherical envelope are found by means of the integral constraints and physical considerations. Cases of a central point source, uniformly distributed sources and conic sources on the outer boundary surface of the media are considered.
