The ground state properties of {sup 3}He and {sup 3}H are calculated using momentum space Faddeev wave functions with the Bonn meson-exchange model for the two-nucleon interaction. These properties include the binding energy, Coulomb energy, asymptotic normalization constants, magnetic moment, and the electromagnetic form factors and radii associated with elastic electron scattering. Identical calculations are also carried out with the Paris and Reid soft-core potentials. With the Bonn potential, the triton binding energy is predicted to within 98% of the experimental value. The charge-dependence of the Bonn potential also allows a successful description of the {sup 3}He-{sup 3}H binding energy difference. The magnetic properties as predicted by the Bonn potential are in excellent agreement with experiment when meson-exchange effects are taken into account. As for the charge properties, only the charge radius is successfully predicted. Calculations of the cross sections for the photodisintegration of {sup 3} He and {sup 3}H are performed in the plane-wave impulse approximation. Attention is given to the sensitivity of the D-state in the nuclear wave functions.
