Abstract
The degree of linear polarization of radiation from an ionized gas is calculated analytically. The analytical results on the resonant transition in Al XII atoms agree (to within 4%) with the numerical results obtained from the ATOM code. The applicability of the analytic expressions derived to the analysis of the degree of linear polarization of radiation from this atomic transition and the related excitation cross section is discussed. The plots of the degree of linear polarization of radiation from an ionized gas as a function of the electron parameters are presented. The question of whether the spectropolarimetry can provide an independent optical diagnostic tool is discussed.
