| Abstract: | The 12C(γ,pn) and 12C(γ,pp) reactions have been studied using tagged photons of energy Eγ = 150–400 MeV. Recoil momentum distributions are compared to the results of Monte Carlo calculations based on a two-nucleon photon absorption model and two different phase space models. The 12C(γ,pn) data at low missing energy are consistent with absorption on 1p2 and 1s1p nucleon pairs. |
