Total and differential charge transfer cross sections inHe2+ + N4+ collisions

Abstract

Charge transfer in the collision system He2+ + N4+has been investigated both theoretically and experimentally forcentre-of-mass energies between 8 and 200 keV. The theoreticalcalculations of the collision process have been carried out inthe semi-classical impact parameter eikonal approachexpanding the electronic wavefunction in a multi-statemolecular-orbital basis with translation factors. Themeasurements of the charge-transfer cross sections wereperformed at an ion-ion crossed-beams experiment.Good agreement between the calculations and the experimentalresults for both total and differential cross sections isobtained.
