“…This raises some interesting questions which may make the triple-coincidence results even more significant. The analysis of the 12 C(e,e ′ p) events at high p m [175] suggests that the FSI contributions are small when the final state is reconstructed to be a 11 B nucleus, but dominate the cross section for more inelastic scattering. Because the experiment reconstructs that nearly 100% of these high-p m 12 C(e,e ′ p) events are associated with a high-momentum recoil nucleon corresponding to an initial SRC (in the PWIA), the majority of the triple-coincidence events must also involve a final-state interaction.…”

One of the primary goals of nuclear physics is providing a complete description of the structure of atomic nuclei. While mean-field calculations provide detailed information on the nuclear shell structure for a wide range of nuclei, they do not capture the complete structure of nuclei, in particular the impact of small, dense structures in nuclei. The strong, short-range component of the nucleon-nucleon potential yields hard interactions between nucleons which are close together, generating a high-momentum tail to the nucleon momentum distribution, with momenta well in excess of the Fermi momentum. This highmomentum component of the nuclear wave-function is one of the most poorly understood parts of nuclear structure.Utilizing high-energy probes, we can isolate scattering from high-momentum nucleons, and use these measurements to examine the structure and impact of short-range nucleon-nucleon correlations. Over the last decade we have moved from looking for evidence of such short-range structures to mapping out their strength in nuclei and examining their isospin structure. This has been made possible by high-luminosity and high-energy accelerators, coupled with an improved understanding of the reaction mechanism issues involved in studying these structures. We review the general issues related to short-range correlations, survey recent experiments aimed at probing these short-range structures, and lay out future possibilities to further these studies.
