The 12C(γ,p) reaction at Eγ=60, 80 and 100 MeV

The angular distribution of the 12C( gamma ,p) reaction has been measured at E gamma =60, 80 and 100 MeV for excitation energies 0-7 MeV in the residual nucleus. The measured cross sections are considerably larger than IPM predictions and are compared with a calculation which uses a Jastrow correlation factor to simulate the effect of two-nucleon interactions.
