We have measured the 3He(e,e'pp)n reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for "fast" nucleons (p>250 MeV/c) peaks where two nucleons each have 20% or less, and the third nucleon has most of the transferred energy. These fast pp and pn pairs are back to back with little momentum along the three-momentum transfer,(More)
This experiment is designed to measure the properties of vector mesons in nuclear matter. At high baryon density the masses of vector mesons are predicted to change due to chiral symmetry restoration. The predicted downward shift of the vector meson masses is 10 to 20%. The photoproduction of vector mesons near threshold can be used to measure the masses(More)
