Abstract We have measured absolute cross sections for proton excitation of the 31 P-,41 S- and 41 D-levels of He in the energy range from 200 keV to 1 MeV. Calibration with a tungsten lamp mounted in the collision chamber and normalization on the high energy first Born approximation 31 P values for protons and electrons were used to obtain absolute data. At 1 MeV the experimental results agree within 10% with the first Born approximation values.
