A semiconductor counter telescope in a bremsstrahlung beam has been used to measure photoproton spectra from /sup 12/C. The bremsstrahlung maximum energy took on the following values: 21.7, 23.4, 25.0, 26.6, 28.2, 29.6, and 31.0 MeV. The photoprotons were detected at an angle 90/sup 0/. From the measured spectra we obtained the energy dependence of the cross sections for the reaction /sup 12/C(..gamma..,p) /sup 11/B with formation of the final nucleus in the ground state and a number of excited states. In the region up to 30.5 MeV the integrated cross section for transitions to the ground state amounts to 73.7% of the total photoproton cross section.
