Ionisation double du magnesium par impact électronique : détermination des sections efficaces différentielles et des section[s] efficaces totales

Abstract : Electron - impact double ionization of magnesium atom (3s2) is investigated theoretically for the case of high incident en[e]rgies (1KeV). An ab-initio calculation is carried out including correlation in the initial - state wave function and distorted wave function for the ejected electrons. The results are compared with the first (e,3 e) data on magnesium atom. For the first time we have calculed different cross sections type of the double ionization (8DCS, 7DCS, 4DCS, 2DCS, DCS) taking into account electronic correlations in the initial state and the effect of the distortion in the final state. This work hasshown the importance of the electronic correlation and the role of the distortion on the different cross sections
