International Journal of Mass Spectrometry,
The processes of helium single ionisation and excitation by proton impact are reviewed for the collision energy region relevant to He
beam fusion edge plasma diagnostics (proton energy 10 < E < 50 keV). Classical trajectory Monte Carlo (CTMC) calculations have been
performed and compared with the existing data. Obtained results for single ionisation are close to available experimental data, while for
excitation they are larger by up to a factor of two. For excitation into high quantum numbers, the n-3 scaling law is verified by our CTMC
