| Abstract: | The line profiles of ArI in the infrared spectral range have been investigated. The radiances of the plasma column has been recorded on the plates using the spectrograph PGS2. For selected ArI lines the spectral distribution of intensity has been measured. The electron concentration and temperature of the plasma has been determined on the basis of the measured half width and total intensity of the hydrogen Hβ line. Using this parameter (Ne, T) the profiles for selected ArI lines have been calculated and compared with those obtained from experiment. The agreement between the theoretical and experimental profiles is satisfactory. |
