Abstract The line profiles of 184.9 nm Hg resonance line emitted from a Hg low-pressure high-frequency electrodeless discharge lamp, containing Hg 198 isotope, have been measured by means of a Zeeman scanning spectrometer at the mercury cold spot temperature values in the range of 0–23 °C. Two different methods were used to determine the real spectral line profile and to separate the instrument function: (i) solving the ill-posed inverse problem by means of the Tikhonov's regularization method; and (ii) the mathematical modelling by means of a non-linear multi-parameter chi-square fit. The real Hg 184.9 nm spectral line profiles, determined by both methods, are compared. Influence of instrumental function, degree of the self-absorption and temperature of the radiating atoms are obtained.
