Abstract

Inclusive photoproton spectra have been measured at five laboratory angles and two photon energies: 159 and 198 MeV. A quasi-monochromatic photon beam, obtained by positron annihilation in-flight on a liquid hydrogen target, was used and the photon spectrum was measured on-line by a pair spectrometer. The experimental proton spectra are well described by assuming a dominant photon absorption mechanism by np quasi-deuteron pairs in the nucleus, provided that rescattering effects are taken into account.
