Complete frequency redistribution
Webnext section, is 1= in the case of scattering in a line with complete frequency redistribution, i.e., with a common frequency probability for both absorption and emission within the line. Line Radiation In the case of line radiation, the Einstein coe cient A21 represents the number of sponta-

WebAug 1, 1999 · The discrete-ordinates method is used to develop a solution to a class of non-grey problems in the theory of radiative transfer. The model considered allows for scattering with complete frequency redistribution (completely non-coherent scattering) and continuum absorption.

WebThis corresponds to the Complete Frequency Redistribution (CFR) case, for which the emission and absorption line shapes coincide and the jump length PDF is independent of the past history. For strong resonance lines with short lifetimes the frequency redistribution is partial since only a few collisions occur before emission, and consequently
