He2+ formation in collisions between He+ ions and Ne atoms

Absolute differential and total cross sections for single electron loss of He+ ions impinging on Ne were measured in the energy range from 2.0 to 5.0 keV. The absolute differential cross sections display a decreasing behavior with increasing angle. The measured electron-loss cross sections show a monotonically increasing behavior as a function of the incident energy and are found to be of the order of magnitude between 10(-5) and 10(-4) Angstrom(2). The total cross section is compared with other available measurements and theoretical models at high energy. An extrapolation of the high-energy data to low energies shows good agreement with the present data
