Abstract

Electromagnetically induced two nucleon emission reactions are sensitive to the interaction between nucleon pairs in the target nucleus. Contributing mechanisms include Meson Exchange Currents (MEC), Delta currents, Final State Interactions (FSI) and Nucleon-Nucleon Correlations (NNCOR). The roles of MEX and Delta currents in two nucleon emission reactions are well established. The task now confronting experimenters is to devise experiments which are sensitive to the interesting NNCOR while minimising the effects of other contributions. This paper reports experiments carried out to measure (gamma,NN) cross sections on 4He and 16O in near super-parallel kinematics where NNCOR are expected to be relatively large and the contribution from Delta currents is suppressed.
