Collisional destruction of fast H(2p), H(3s) and H(3d) hydrogen atoms in collision with He, Ar, H2, N2 and O2

In the energy range 5-100 keV the collisional destruction of H(3s), H(3d) and H(2p) atoms in He, Ar, H2, N2 and O2 has been investigated. In the case of 3s and 3d states the measured cross sections which are subject to errors in the range 20-30% are in general agreement with the cross sections predicted by a simple model in which the orbital electron and the proton nuclear core are assumed to act independently on the target. Collisional destruction cross sections for n=2 and 3 were found to be independent of the l value within the experimental error, typically 20-30%.
