  One-nucleon emission processes induced by photon absorption are studied by
considering short-range correlations effects. At energies above the giant
resonance region the validity of the direct knock-out model has been tested by
comparison with continuum Random Phase Approximation results. Nucleon
re-scattering effects have been considered by using an optical potential. The
role of the electromagnetic convection, magnetization and meson exchange
currents has been investigated as a function of both excitation energy and
momentum transfer. The short-range correlation effects have been studied by
using various correlation functions. We found that the nucleon photo-emission
cross section is rather sensitive to the presence of short-range correlations
at large values of nucleon emission angle. In this region, however, the effects
of meson exchange currents are even larger than those produced by short-range
correlations.
