[en] The total and the 90.deg. differential cross sections for the photoproton reaction 16O(γ,p3)15N* leading to the third 3.2- excited state of 15N are calculated for photon energies up to 120 MeV by using the continuum random phase approximation (CRPA) approach. A correlated source function, which makes the numerical calculation possible, is used in solving for the continuum response function. The structures of the theoretical cross sections are in good agreement with the corresponding experimental data
