  We show examples of neutron capture, photo dissociation and Coulomb
dissociation processes, relevant for studying nuclear structure properties of
some light nuclei. In the case of the neutron capture, we show how interference
effects among the direct and resonance processes can be accounted for. The same
interference effect is shown to play an important role in the photo
dissociation of 9Be, for excitation energies just above the neutron emission
threshold. Finally, the Coulomb dissociation of radioactive projectiles is
shown to provides basic structure information on neutron rich exotic systems.
The example of the 19C halo structure is shown.
