Abstract

We have measured the [Formula presented] reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for “fast” nucleons ([Formula presented]) peaks where two nucleons each have 20% or less, and the third nucleon has most of the transferred energy. These fast [Formula presented] and [Formula presented] pairs are back to back with little momentum along the three-momentum transfer, indicating that they are spectators. Calculations by Sargsian and by Laget also indicate that we have measured distorted two-nucleon momentum distributions by striking one nucleon and detecting the spectator correlated pair.
