Measuring two nucleon knockout reactions from light nuclei can test our knowledge of nuclear bound state and continuum wave functions as well as our models of one- and two-nucleon currents. We have used the Jefferson Lab CLAS, a 4π spectrometer, to measure kinematically complete 3N breakup of 3He with 2.2 and 4.4 GeV electrons. When one nucleon carries away most of the kinetic energy, there is a large peak at 180° in the opening angle of the other two nucleons, indicating the presence of NN correlations. These correlations, unlike those measured in other reactions, appear to be unaffected by two nucleon currents such as MEC or IC.
