摘要：
The results of tagged photon measurements of the O-16(gamma, pn), O-16(gamma, pp) reactions, carried out with photons of energies 80-131 MeV, are presented. Missing energy spectra for both reactions, with an energy resolution of 7 MeV have been obtained. The O-16(gamma, pn) missing energy spectrum is very similar to that recently measured for the C-12(gamma, pN) reaction. In both cases the recoil momentum distributions are quantitatively described by a quasideuteron mechanism. Using normalisation factors based on this mechanism the average cross section for the O-16(gamma, pn) reaction, for nucleons ejected from the lp shell, is 510 +/- 95-mu-b. The corresponding cross section for the O-16(gamma, pp) reaction is 10.0 +/- 3.0-mu-b.
