A b s t r a c t . The charge dependence of the nucleon-nucleon force can be derived from the lowenergy scattering parameters. The p-p and n-p parameters were measured in direct scattering experiments. The n-n parameters a , , = (-16.70 j , 0.38) fm and r,, = (2.78 & 0.13) fm have been determined from few particle reactions. The difference of the scattering lengths (u,, -a,,) 4 7 fm demonstrates the violation of the charge independence. Information on the charge symmetry is still doubtful due to the inaccuracy of the charge correction for the p-p parameters. Whereas the n-n and the charge corrected p-p parameters known a t present yield a weaker n-n force than the p-p force, the opposite result follows from the binding energy difference for 3He and 3H and the meson theory of the nuclear forces.
