(p,2p) and (e,e'p) on 2H and 3He

In this paper the author discusses results of (e,e'p) and (p,2p) reactions on 3He, 4He and 2H at intermediate energies. First, the advantages of studying both knock-out reactions at 3He are pointed out. Their spectral functions obtained using the PWIA are mutually compared and also compared with existing theoretical calculations. Then the physical situation with regard to 4He is described. Momentum distributions of both reactions are compared. Some remarks on the reliability of the DWIA are made. Finally, the knock-out reactions at 2H are discussed. The electron reactions show good agreement with theoretical calculations, but the proton reactions do not. Some origins of these deviations are suggested (e.g. delta-excitation). (Auth.)
