摘要：

The He-4(gamma, p)H-3 reaction cross section has been measured with tagged photons of energy 81-158 MeV. Protons were detected over the angular range 55-degrees-125-degrees. The scaling of the data as a function of momentum mismatch has been examined for two reaction models, the modified quasideuteron mechanism and quasifree knockout. Both models show clear scaling behaviour but comparison of the predicted and measured scaling function shapes favours the modified quasideuteron mechanism at momenta up to approximately 500 MeV/c.
