Radiative Transfer in Spherical Shell Atmospheres with Radial Symmetry

Abstract
In recent years, the need to allow for the effect of curvature on the formation of spectral lines has been recognized not only in the fields of planetary and stellar atmospheric physics but also in the field of neutron transport in spherical reactors. This paper is of interest in these and related fields. Initial value systems are obtained for the scattering and transmission functions and emergent intensities for inhomogeneous, anisotropically scattering spherical media both with internal and external sources and with various types of cores.
