Abstract
Laboratory plasmas can be characterized by Optical Emission Spectroscopy techniques by using Hydrogen Balmer series lines. The line shape is the result of the convolution of the several internal process occuring in plasma. The Stark effect over the Hydrogen emitter atom has been studied in a limited range of plasma parameters, obtaining a profile which is the result of a sum of a given number of Lorentzian functions for the Hα and Hβ line. In this paper, we have extended this analysis to cover a wide range of plasma conditions for the Hα line. The number of Lorentzian functions depends on the contribution of ion collisions around the Hydrogen emitter atom and their mobility in comparison with that of electrons.
