- Abstract
- We have measured the He3(eeppn) 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, indicating that they are spectators. We provide the cross section of Correlated Pair Relative and Total Momentum.
