Abstract
Present day results for few-nucleon bound state and scattering observables based on modern high precision nuclear forces are briefly reviewed. While i n relation to NN forces of that type three-nucleon (3N) forces are mandator y for binding energies and for quite a few 3N scattering observables their effect is rather small in two-nucleon correlation functions as demonstrated for He-3 and He-4. The old idea of the Coulomb sum rule as a way to extrac t the pp correlation function is reconsidered and the need for more accurat e data is pointed out. It appears to be an ideal case to probe properties o f the density operator and the ground state wave functions without disturba nces of final state interactions (FSI). In the 3N system below the pion thr eshold FSI is well under control and therefore the exclusive process He-3(e , e'NN) is also a very good test case for correlated nuclear wave functions and electromagnetic current operators. One specific kinematics is emphasiz ed, which can lead to insights into the correlated ground state wave functi ons with little disturbance of FSI. Finally exclusive photodisintegration o f He-3 is regarded, which appears to be promising to identify 3N force effe cts.
