Abstract

The production of η mesons at an excess energy of Q=72 MeV has been studied in the reaction pp→pp(η)γγ. Preliminary angular distributions and projections of invariant masses are presented. Deviations from phase space behavior is observed, indicating the presence of different partial waves.
