摘要：

The cross section of the He-3(gamma,pp)n reaction has been measured for the first time over a wide photon energy and proton angular range (200 MeV less than or equal to E(gamma) less than or equal to 800 MeV; 20 degrees less than or equal to theta v(p)(lab) less than or equal to 160 degrees) using the large acceptance detector DAPHNE at the tagged photon facility of the MAMI microtron in Mainz. The wide kinematical coverage of the measurement has allowed a detailed analysis of three-nucleon absorption mechanisms. A model developed by Laget explains the main characteristics of the data in the Delta resonance region.
