Calculation Of Ionization Rate For Li+using Of Bi -maxwillian Distribution Function

Résumé: Electron impact ionization has been an interesting problem for many years, with its important application in fusion reactors (plasma edge processes.. ), radiation damage in biological matters( including cancer treatment). There is a vast effort to fully understand the electron emission during ion-atom collisions from both the experimental and theoretical perspectives. We report in this paper calculation for cross section and rates coefficients for electron-impact ionization. The FAC code (Flexible Atomic Code) is adopted for calculating cross section and for determining the energy levels. We study the influence of electron energy distribution functions on the calculation of ionization using a bi-Maxwellian energy distribution in the case of weak values of hot electron fractions. The use of bi-Maxwellian energy distribution showed the sensitivity of these rates to the forms of the electron energy distribution. The results are in good agreement compared to those found in the literature.
