Kopsavilkums

The Hg 253.7 nm spectral line profiles, emitted from the mercuryargon high-frequency electrodeless discharge lamps (HFEDL) have been measured by means of a high-resolution scanning FabryPerrot interferometer at the mercury cold spot temperature value at 20 °C, different discharge current and buffer gas values. The deconvolution procedure by means of the Tikhonov's regularization method was performed to obtain the real spectral line shape. The influence of the instrumental function and absorption, real width of the Hg 253.7 nm resonance line and temperature of the radiating atoms are obtained. The results were compared with the results of the nonlinear multiparameter mathematical modeling by means of a nonlinear multiparameter χ² fit.
