[en] The aim of the experimental program is the determination of the nucleon-nucleon amplitudes at medium energy. Experiments described include D/sub SS/, D/sub LS/, D/sub SL/, D/sub LL/, and P for p-p elastic scattering, the measurement of polarization observables in ppvector → pvector π⁺nu and ppvector → ppvector π, and measurements of the spin rotation parameters for pvector d → pvector d elastic scattering at 496, 647, and 800 MeV. Also, progress on an energy dependent proton-carbon analyzing power fit is reported. Current approved LAMPF proposals are described and 1983 publications are listed
