Electron Transfer in p-Ar Collisions at keV Energies

Absolute differential and total cross sections for single electron capture of H+ ions impinging on Ar atoms in the energy range of 0.5-5.0 keV and scattering angles from -5.0 deg. to 5.0 deg. are reported. The absolute differential cross (DCS) sections for all acceleration energies shows a decreasing behavior with increasing angle, showing an overall decrease of six orders of magnitude. The total cross section is found to be between the range of 4.9 and 15 A2. The total cross sections display an increasing behavior as a function of the incident energy. The absolute differential and total cross section are compared with other available measurements and a recent theoretical approach.
