On the radiative transfer in a spherical medium

The solution of the spherical radiative transfer problem is described for absorbing and scattering medium. The Fourier modes method is used to obtain solutions for linearly anisotropic case in a homogeneous sphere. The calculations are extended to the conservative case that set a limit for the results. It has been shown that all results converge to this limit. Based on a semi-analytic approach, numerical calculations are performed and compared to the results of several previous works.
