Single electron loss in the collisions of C3 + and atomic hydrogen

doi:10.1088/1674-1056/19/9/093401

Abstract This paper studies the projectile electron loss cross sections of C^{3 +}colliding with atomic hydrogen in the frame work of extended over-barrier model at intermediate velocities (25 keV/u–600 keV/u). The electron loss is calculated in terms of the interaction between the screened target nucleus and the active projectile electron and of the interaction between projectile electron and target electron. Compared with the convergent close-coupling calculations, screening and anti-screening calculations, this model satisfactorily reproduces the experimentally obtained energy dependence of the electron-impact ionisation cross sections and the single electron loss cross sections over the energy range investigated here.

Keywords: single electron loss over-barrier model
