  We present a model to describe the emission of two protons in electron
scattering experiments. The process is induced by one-body electromagnetic
operators acting together with short-range correlations, and by two-body Delta
currents. The model includes all the diagrams containing a single correlation
function. The sensitivity of the cross section to the details of the
correlation function is studied by using realistic and schematic correlations.
Results for the 16O nucleus are presented.
