Multiple Electron Transfer in Collisions of Highly Charged Ar Ions on Argon Atoms

Abstract

Electron Capture and transfer ionization by Ar(8–12)+ in collisions with argon atoms were studied by using the position sensitive and time-of-flight techniques. Some of the measured projectile charge changing cross sections (σq,q−k) and phenomenological cross sections (σrq,q−k) are reported in this paper. The measured cross sections are compared with the predictions of the molecular Coulombic overbarrier model by considering the autoionization decay and electron evaporation of multiply excited states in projectiles and recoil ions respectively.
