Trinucleon charge densities and three-nucleon forces

Trinucleon charge densities and charge form factors are calculated in impulse approximation for a large set of wave functions obtained from solving the Faddeev equations for diverse combinations of four two-body force models and three three-nucleon force models. The three-nucleon forces improve the form factor predictions in the region of the secondary maximum slightly, but the experimental data are still substantially higher than the theoretical predictions, while the positions of the theoretical first diffraction minimum and secondary maximum are too high
