(p,2p) angular correlations for various p-shell nuclei are analyzed in the distorted-wave Born approximation with simple shell-model assumptions for the struck particle. The object is to define the limits on the information that can be obtained about nuclear structure from present experiments and to suggest how experiments should be improved. It is found that a simple shell-model wave function for the struck particle can be quite well defined by fitting present experimental data but that the choice of optical-model parameters is highly ambiguous. The ambiguity extends to the determination of the effective two-body potential and the necessity for configuration mixing. The rms radius of the proton distribution obtained from (p,2p) curve fitting agrees well with that obtained from electron scattering. The primary needs is for better energy and angular resolution.
