Digging deeper in nuclear matter

This trend article presents a survey of the nuclear research programs of the secton NIKHEF-K with the 500 MeV electron-accelerator MEA in Amsterdam. After an introductory review of the principles of studying nuclei with electron-scattering experiments, some characteristic examples are discussed of inclusive (e,e')-experiments, in which only the scattered electron is detected, and exclusive (e,e'X)-experiments, in which the electron as well as the reaction product X are measured in coincidence. Finally an experiment with the 13C(γ,π-minus)13N is discussed which includes the study of pion-degrees of freedom in the nucleus. (H.W.). 7 figs
