Abstract

TThe results of tagged photon measurements of the 16O(γ, pn) and 16O(γ, pp) reactions, carried out with photons of energies of 80–131 MeV, are presented. Missing energy spectra for both reactions, with an energy resolution of 7 MeV have been obtained. The 16O(γ, pn) missing energy spectrum is very similar to that recently measured for the 12C(γ, pN) reaction. In both cases the recoil momentum distributions are quantitavely described by a quasideuteron mechanism. Using normalisation factors based on this mechanism the average cross section for the 16O(γ, pn) reaction, for nucleons ejected from the 1p shell, is 510 ± 95 μb. The corresponding cross section for the 16O(γ, pp) reaction is 10.0 ± 3.0 μb.
