Özet
Differential cross sections for single-electron capture by Ar-q+ ions (q = 4-8) from He and Ar have been measured at impact energies between 600 and 2500 eV, and projectile scattering angles between 0 and 25 mrad. The experimental angular distributions contain a main peak lying near a critical angle theta(c), which corresponds to capture at an impact parameter equal to the crossing radius. The results are quantitatively explained by a semi-classical model based on Coulomb potential energy curves.
