Differential scattering cross section for excitation in He+Ne collisions

The impact parameter method is used to investigate the excitation of the (2p53s)1P of Ne in He+Ne collision. It is assumed that excitation occurs mainly by a transition from the B2 Sigma state to the excited C2 Sigma state in the vicinity of the pseudo crossing of their respective potential energy curves. The potential parameters of Sidis and Lefebvre-Brion (1971) are adopted. The calculations which have been made at impact energies 0.7 keV and 1.58 keV are in very good agreement for tau <3 keV deg with the experimental results of Baudon et al. (1970). Limitations of the methods used are discussed.
