Elargissement Electronique Dans Les Plasmas Relativistes : Interaction Deutsch Et L’effet D’écran Exacte
Résumé: The line shapes of the emission and absorption of the atoms is used as a diagnosis of temperature and density in the plasmas; they present the distribution of the intensity around the central frequency of the radiation. Electronic broadening has been studied in several texts especially within the work of the classical theory for isolated lines. Very fast electrons will create a very quickly variable field; its perturbation will be calculated using the theory of individual collisions. It will also be necessary to take into account the dipole moment of the emitter ion. The field of each of the disturbing particles will be Coulomb. For a hydrogenoid ion, and in the impact theory, an electronic collision operator was given, where the potential was considered screened by electrons. In our work we calculated the electronic collision operator, taking into account the effect of ions, and the relativistic effect and the quantum effect. The correction on the potential reaches a 100%
