The trinucleon charge form factors are studied for various nuclear interaction models with possible three-body force and meson-exchange-current effects included. A unitary transformation method of generating three-body forces is discussed. Various meson-exchange effects, including pair and recoil currents as well as that of the ..pi..NN vertex function, are investigated. The calculations show that the strong potential dependence of the /sup 3/He charge form factor in the impulse approximation diminishes considerably when meson-exchange effects are included. Exchange effects in /sup 3/H are smaller than in /sup 3/He and do not reduce the potential dependence. By including meson-exchange currents and three-body forces, good fits to the available /sup 3/He and /sup 3/H form factor data for 0.5 fm/sup -2/ < or = q/sup 2/ < or = 12 fm/sup -2/ are obtained without sacrificing a satisfactory triton binding energy. The position of the diffraction minimum is correctly predicted and the height of the second maximum is improved to about half of the experimental value. (AIP)
