Abstract

Differential cross sections for He single ionization in fast p and p impact are presented and compared to theory. To investigate possible correlation effects on the double ionization cross section in p collisions the in momentum space complete differential cross sections for fast p on He transfer ionization processes has been investigated and the influence of correlation effects, i.e. the influence of so called “off-shell” contributions in the He ground state wave function, has been measured. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

Abstract

We have investigated the transfer ionization process in fast collisions between protons, stored in the heavy-ion storage and cooler ring CRYRING, and a cold supersonic helium gas-jet target: H+ + He → H + He2+ + e-. We have refined the COLTRIMS (COLd Target Recoil-Ion-Momentum Spectroscopy) technique by applying time-varying fields in the recoil-ion-momentum spectrometer to block random singly charged helium ions from single-ionization events. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]

3. Secondary Molecular Ion Emission In Binary Projectile-Surface Collisions.

Abstract

Secondary molecular ions, emitted from a LiF target bombarded by a MeV argon beam, are analyzed by a XY-TOF detection system. This new method allows, for each emitted ion, simultaneous measurement of its time-of flight (TOF) and its impact coordinates (XY) on the detector surface, after acceleration by a homogenous electric field. Angular distributions and initial velocities for atomic (H+ , Li+, C+) and for molecular (H[sub n][sup +], C[sub m]H[sub n][sup +]) ions are determined. The analysis reveals different emission processes, among them a unexpected emission of fast molecular ions from binary collisions. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
