Absorption and emission line profile coefficients of multilevel atoms - II. Velocity-averaged profile coefficients.
Abstract
Starting from the atomic profile coefficients of a multilevel atom derived in the previous first part of this paper, the authors consider the velocity-averaged line profile coefficients appearing in the radiative transfer equation for the important special case that the velocity distribution of atoms in the ground state is Maxwellian and that the streaming of excited atoms is negligible.
