Modifications of delta in nuclear medium

In the experiments at the Mainz Microtron, MAMI, D0 particles in the electron scattering reactions 12C (e, e&cent ; ; D0)11C have been produced in nuclear medium. The three high-resolution magnetic spectrometers of the A1 collaboration have been used in triple coincidence measurements 12C(e, e&cent ; ; pp-)11C. Indications for substantial changes of delta properties in the nuclear medium have been obtained. Because of low statistics, these results cannot yet be taken as conclusive. A new setup for measurements at MAMI with silicon detectors for proton detection, which subtend larger solid angle, is described.
