Abstract
With a beam of neutral particles (inert gas atoms and molecules of H2 and N2), produced by charge-exchange, the ionization efficiency up to energies of 300 eV and the threshold in collisions with particles of the same kind were investigated. The threshold, determined by extrapolating the experimental curves, is (in good agreement with the impact conservation laws) twice the ionization energy. The rise of ionization with energy (up to 100 eV) can be expressed by a power-function with a mass dependent exponent between two and three. There was no hint for the ionization to go through a maximum in the lower energy range.
