Abstract
Coherent and incoherent pi(0) photoproduction off the deuteron has been mea sured for incident quasi-monoenergetic photons in the energy range from pi( 0) threshold up to 300 MeV using the TAPS setup together with the Glasgow t agger at MAMI. Integral and differential cross sections over the full angul ar range have been obtained. Coherent and incoherent production are found t o exhibit very different angle and energy dependences. The sum of both proc esses, the total pi(0) production off the deuteron is quantitatively extrem ely well described by a pure quasifree model, whereas the data for coherent and incoherent channels necessitate strong FSI effects for their descripti on. Finally upper limits for the production of dibaryon resonances in this reaction have bees obtained.
