  Some present day results for few-nucleon bound state, two-nucleon correlation
functions and scattering observables are briefly reviewed. The old idea of the
Coulomb sum rule as a way to extract the pp correlation function is
reconsidered. It appears to be an ideal case to probe properties of the density
operator and the ground state wave functions without disturbances of final
state interactions (FSI) in exclusive electron scattering on 3He. Also
exclusive photodisintegration of 3He is regarded which appears to be promising
to identify 3N force effects.
