The proposed research is directed toward the exposition of hadron structure, both at the nuclear and meson levels. Photon and hadron beams will be used to excite sub-nucleon currents in proton and few-nucleon targets. The measurements to be performed include Compton scattering, meson production and nucleon knock- out reactions on few-nucleon systems at (1232) energies, and exotic-meson and baryon resonance production with high energy beams at BNL and CEBAF.
