Abstract
New possibilities of using the Voigt profile are suggested for investigation of characteristics of radiation absorption in a gas. For this purpose, the absorption coefficient in the line center and the total absorption linewidth are determined without knowledge of a dependence of the shape of the Voigt profile on the frequency. Asymptotic values of these characteristics are determined. Based on this approach, the temperature of ions in ultracold plasma is determined and compared with the available experimental data.
