Description
A breakdown of the impulse approximation is studied in pion photoproduction on 3He at high momentum transfers. The usual distorted wave impulse approximation formalism with Faddeev wave functions that works well for small momentum transfers deviates from experimental measurements by up to 2 orders of magnitude for Q2>6 fm-2. It is found that the explicit inclusion of two-body mechanisms, where the photon is absorbed on one nucleon and the pion is emitted from another nucleon, removes most of the disagreement with the data
