Three-nucleon hadronic and electromagnetic reactions with -isobar excitation

Three-nucleon hadronic and electromagnetic reactions are described. The description uses the purely nucleonic charge-dependent CD-Bonn potential and its coupled-channel extension CD-Bonn + . Exact solutions of three-particle equations are employed for the initial and final states of the reactions. The -isobar excitation yields an effective three-nucleon force and effective two- and three-nucleon currents beside other -isobar effects; they are mutually consistent.
