The data on the (p,2p) reaction on 1p shell nuclei at incident proton energies of 155-185 and 460 MeV and on 2s-1d shell nuclei at incident proton energies of 156 MeV have been analysed in the Distorted Wave Impulse Approximation (DWIA) using the di-proton model representation for the three- body final state. The experimental spectroscopic factors S[exp] obtained by comparing the computed cross-section with the experimental one are compared with the theoretical spectroscopic factors predicted from the work of Cohen and Kurath in lp shell nuclei and from. SU[3] and the collective model coupling schemes in 2s-1d shell nuclei. It is found that provided the distortion of the incident and the outgoing protons is properly taken into account and the resolution of the experimental data is good, this reaction can be used to study the single hole states in nuclei. Also, it is found that the experimentally deduced spectroscopic factors are very sensitive to the description of the single particle wave-function of the bound proton. Finally from the calculations of the angular distributions for proton energies in the range of 160 MeV to 1 GeV, it is found that the detailed behaviour of the single-particle momentum distribution in nuclei can be investigated with much greater certainty at the higher energies than is possible at proton energies below 200 MeV.
