| We have measured the 3He(e,e′pp)n reaction at 2.2 and 4.4 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 or ‘leading’ nucleon carries most of the transferred energy. These fast nucleon pairs (both pp and pn) are back-to-back and carry very little momentum along , indicating that they are spectators. Experimental and theoretical evidence indicates that we have measured NN correlations in 3He(e,e′pp)n by striking the third nucleon and detecting the spectator correlated pair. |
