Direct and Charge-Exchange Collisions in Argon Ion + Carbon Monoxide at Low KEV Energies.
Ar('+) + CO collisions are studied at energies of 1.0, 2.0, and 3.0 keV in the angular range 0.0 to 3.0 degrees. Energy losses in the direct collision are measured and the participating states are identified. Charge-exchange in 1.0 keV Ar('+) + CO collisions is also investigated using time-of-flight techniques at selected angles in the same angular range. Measurements of the charge-exchange probabilities at 0.75, 1.0, 2.0 and 3.0 keV are also made. In addition, reduced cross-sections for the direct and charge -exchange collisions are determined. The results suggest a model useful in explaining collisional interactions in ion-molecule scattering.
