Measured values of voltages in maximums of intensities of lines are connected with electronic temperature with the following dependence:
lg(Vki/Vlm)=lg[fikgil2lmSlm/(fmlgml2
kiSik)] - 5040(Ek-El)/Te
where fik and fml are powers of oscillator, gi and gmare statistic weights, lki and llm- waves lengths, Vki and Vlm, Sik and
Slm- voltages at the outlet of the booster of the direct current in max. of intensity and spectral sensitivities for waves lengths of transitions ki and lm respectively, Ek and El- energies of transitions( EV) , Te - electronic temperature (K).
Hence the electronic temperature can be calculated :
