The cross sections of the $^{16}O(\gamma$,n) reaction were measured with tagged photons of 50-70 MeV and compared with the equivalent ($\gamma$,p) reaction and various theoretical calculations. The implications for the dependence of the ($\gamma$,N) cross section on meson exchange currents and final state rescattering are discussed.
