Abstract

I start by reviewing existing pp measurements with particular emphasis on the recent 221 MeV pp measurement at TRIUMF which permitted the weak meson-nucleon coupling constants h^pp_ρ and h^pp_ω to be determined separately for the first time. I then review np experiments, with specific details of the np → dγ experiment now under preparation at Los Alamos National Laboratory. This experiment will provide a clean measurement of the weak pion nucleon coupling, f_π. Finally, I discuss ep parity violation experiments, particularly the Gzero experiment under way at Jefferson Lab in Virginia. This experiment will measure the weak form factors G_E^z and G_M^z, allowing the distribution of strange quarks in the quark sea to be determined.
