Computer-simulation technique applied to the study of hydrogen Stark broadening by plasmas

A systematic study of ion-dynamics effects in the first three lines of the Lyman and Balmer series of hydrogen has been carried out over the ranges 10²²⁻⁻{10}²³$ ${m}^{{{-}}3}$ and ${10}⁴⁻⁻2×{10}⁴$ K by means of a simulation technique that takes into account the joint effect of ions and electrons. The results obtained considering static ions match the results obtained through time ordering of the unified theory. The inclusion of ion movement in the simulations leads to excellent agreement with experimental data.
