Photoprotons produced in Li, Be, B, and C targets by bremsstrahlung with a peak energy of 335 MeV were observed at eight angles between 20° and 96° in the laboratory. Protons with energies between 140 MeV and 192 MeV were detected by means of a scintillation counter telescope which simultaneously observed three adjacent energy bins. Corrections to the data for nuclear absorption in the target, multiple scattering in the target and counter telescope, pion contamination, and other small effects have been made. The results are compared with Levinger's quasi-deuteron model. The width of the momentum distribution for the quasi-deuteron inside the nucleus and the differential cross section for the photodisintegration of the quasi-deuteron were used alternatively as adjustable quantities in fitting the data. If experimental data for the free deuteron photoeffect are used, it is found that a fairly wide momentum distribution with tails falling more slowly than those of a Gaussian is required for agreement with this measurement.
