Short range correlations in nuclei are interesting because they are necessary to explain the stability of nuclei against collapse. From this follows that they are related to the internal structure of nucleons which is still poorly understood at low energies. Three experiments relevant to this context are presented. In an exploratory experiment of the [sup 12]C(e,e[sup ′]pp) reaction with a 4π-BGO ball and a high resolution magnetic spectrometer of the three spectrometer setup at the Mainz Microtron MAMI the optimal kinematical region for a study of short range correlations is found. In an selective experiment of the [sup 16]O(e,e[sup ′]pp)[sup 14]C reaction using all three spectrometers models of the reaction mechanism and effects of a hard and soft core of the N N potential are studied. In the [sup 12]C(e,e[sup ′]pπ)[sup 11]C reaction again using all three spectrometers evidence for narrow bound Δ states in [sup 12]C is derived which may be related to the very short mean free path of the Δ-decay πs in nuclei. © 2000 American Institute of Physics.
