J. ; Siewert, C. E. Abstract The (singular) eigenfunction-expansion technique is used to construct solutions to a general class of nongray-model problems in the theory of radiative transfer for plane-parallel media. The model considered allows for completely incoherent scattering and continuum absorption, both of which are assumed to be independent of depth. The radiation intensity is obtained for an arbitrary space-dependent Planck function in a semi-infinite atmosphere. In addition, simplified results are obtained for the special cases where the Planck function varies either linearly or exponentially with the optical depth in the continuum. Solutions are obtained in terms of H4unctions which can be calculated once the frequency-dependent scattering and absorption coefficients are specified.
