For exclusive and diffractive reactions in e-A scattering it is essential to detect the neutron of the nuclear break up in the direction of the outgoing beam. The plots show the angular distribution of these neutrons depending on the excitation energy of the nucleus.

For exclusive and diffractive reactions in e-A scattering it is essential to detect the neutron of the nuclear break up in the direction of the outgoing beam. The figure below shows the scattering angle distribution for breakup neutrons from a gold nucleus for different excitation energies of the nucleus.
