Summed energy spectra are studied that are displayed by protons emiited in coincidence in (p,2p) reactions induced by 155-Mev protons on the following target nuclei: Li/sup6/, Li/sup 7/, B/sup 10/, B/sup 11/, and C/sup 12/ Two telescopes, each wi th 2 plastic scintillators and 1 NaI total-absorption scintillator, are used to detect the product protons. The summed energy spectra exhibit generally 2 well-defined peaks, which define the binding energy. Angular correlation distributions are obtained for those events un er each summed energy peak for which the 2 product protons are emitted in a plane symmetrically on each side of the incident beam and have approximately the same energ . Applying the Born approximation and neglecting nuclear absorption, momentum density distributions are deduced for protons in the target nuclei. The high-binding- energy proton distribution presents a maximum for zero momentum, characteristic of an s state. and the lower-binding-energy proton distribution presents a minimum for zero momentum, characteristic of an p state, except in the case of Li/ sup 6/. Parameters of these distributions are given, which permit comparison among the various target nuclei. (auth)
