Abstract

Recoil-ion momentum spectroscopy (RIMS) has been applied to obtain differential single and multiple ionisation cross sections in energetic, ion-atom collisions. Investigating various collision systems, different aspects of the multiple ionisation reaction have been elucidated: The ionisation collision dynamics, the role of many-body interactions, has been explored for single ionisation of He by 0.3 and 0.5 MeV proton impact measuring the transverse momentum of the recoil-ion in coincidence with that of the projectile; deviations from two-body kinematics have been observed. For the 1.4 MeV/u U32+ on Ne collision system multiple ionisation coincident with single electron capture of the projectile has been measured in dependence of the recoil-ion transverse momentum. In a third experiment, 1.4 MeV/u U32+ on Ar, the contribution of autoionisation processes to the production of Ar6+ ions is investigated: Part of the Ar6+ ions were found to be produced with recoil-ion momenta typical for Arsr5+ production.
