The three body photodisintegration of 3He has been measured with the CLAS detector at Jefferson Lab, using tagged photons of energy up to 1.55 GeV. The acceptance of the spectrometer allowed for the first time to cover a wide momentum and angular range for the two outgoing protons. The goal of this experiment was to investigate the three-nucleon interaction in 3He. According to calculations of Laget, by selecting certain kinematic regions the two- and three-body contributions can be distinguished. Preliminary results are discussed and compared with the theoretical predictions.
