حساب معامل التصادم الإلكتروني في البلازما بإستخدام تفاعل دوتش- ديباي

Abstract

The lines spectrum responds to the different interactions between the transmitter and the perturbers which preceded or accompanied the emission, by a broadening and/or a displacement. The average value of the electronic effect is often replaced by an electronic collision operator. In this thesis, this operator is calculated for isolated lines without fine structure. The average effect of these collisions is calculated with the initial velocity according to the Maxwell velocity distribution. Then we consider the movement of the electron around the transmitting ion, where is the interaction taken contains the Coulomb effect, quantum effect and screen effect, we called the potential of Deutsh-Debye. We obtained, for the first time, a collision operator with a potential of Deutsh-Debye. Many of comparison were made for various values of the electronic density, of the atomic number, and of the temperature.
