【 摘 要 】

This paper is based on the study of the emitted radiation by electrical discharge plasma, caused in the helium a pressure of 4.8 Torr, a power MW of 108W. The study numerical model allows the identification of several spectral lines. With the Boltzmann method the study have calculated the electronic temperature (Te=3.23eV), it corresponds to the classification scale of plasmas. The application of the Saha law gives the electronic density of the electrical discharge plasma (Ne=3.67 10 13 cm-3). The calculated theoretical spectra are in good agreement with the experimental ones.
