Non-Coherent Scattering: I. The Redistribution Function with Doppler Broadening

Abstract

The redistribution in frequency of radiation scattered from moving atoms is examined in some generality, allowing for the different types of scattering which occur in the atom's rest frame under different circumstances. Some general formulae are obtained and a number of explicit results are given. Finally some attention is devoted to the properties of the redistribution functions and to the methods which may be used for computing them.
