Hard deuteron photodisintegration has been investigated for 20 years, as its cross section follows the constituent counting rule and it provides insight into the interplay between hadronic and quark‐gluon degrees of freedom in high‐momentum transfer exclusive reactions. We have now measured for the first time hard pp‐pair disintegration in the reaction γ using kinematics corresponding to a spectator neutron. Cross sections were measured for 90° c.m. at 8 beam energies, from 0.8 to 4.7 GeV. Preliminary results will be presented and compared to the hard deuteron photodisintegration data.
