Photoproton spectra from the /sup 19/F(..gamma..,p) reaction were measured at various bremsstrahlung end point energies in the giant dipole resonance region. Absolute cross sections for eight partial photoproton channels were determined with the use of an artificially constructed quasi-monochromatic photon spectrum. Their integrated cross sections were compared with spectroscopic factors for proton pickup reactions leading to corresponding residual states. The (..gamma..,p/sub tot/) cross section was derived from proton yield measurements. These data lead to an estimated semidirect contribution to the photoproton reaction of at least 60%, and to an approximate determination of the configurational splitting.
