The photonuclear and electronuclear Saclay's activities

Research is carried at the 700 MeV linear electron accelerator of Saclay (ALS). Among the results obtained these years, we note the most significant ones: the study of the reaction 3He(γ,p)np, i.e. the photodisintegration of helium-3 without pion emission, has been developed. At the same time, a method for measuring the reaction 3He(γ,pp)n, in which two protons are detected in coincidence, has been improved. The comparison of electron-nucleus and positron-nucleus scattering has just been undertaken. The completion of the detection systems placed in the focal planes of the two high resolution magnetic spectrometers has given an emphasis to the studies of reactions of the type (e,e'p), where the scattered electron and the proton ejected from the nucleus are detected in coincidence
