Asymmetric electron capture in HCI collisions with rare gas dimers

Abstract

Low-energy collisions between different rare gas dimers (Ar2, Ne2) and different projectiles (O3+, Ar9+, Xe20+) show that the weight of the different fragmentation processes, Coulomb explosion and Radiative Charge Transfer, strongly depends on the projectile charge state. This result is understood in term of impact parameter from which the electrons are captured on the projectile. © Published under licence by IOP Publishing Ltd.
