Description
Starting with the recent work of Cooper et al., a suitable form of the normalized redistribution function relevant for a treatment of redistribution in the presence of velocity-changing collisions is presented. Attention is devoted to provide practical estimates of the ratio between the usual line-broadening parameters and the velocity-changing rate. It is shown that for virtually all cases of astrophysical interest the effect of velocity-changing collisions is quite negligible. 31 references
