Abstract

The isobar-hole formalism for pion-nucleus interactions is applied to coherent π0 photoproduction on nuclei. The unifying features of this approach for elastic scattering and photoproduction are discussed, and the relationship to distorted-wave impulse approximation calculations and the phenomenological doorway model are examined. The results are presented for O16(γ,π0)O16 and show a large suppression from the impulse approximation prediction.
