The coherent meson scattering off heavy nuclei with the production of two particles in the final state is investigated. We obtain the form factors for the direct production of the final state and through intermediate particles, unstable ones that can decay inside the nucleus and virtual ones. The cases of scattering both in the Coulomb and in the strong field of the nucleus are considered. This work is stimulated by an experimental study of the chiral anomaly in a beam of charged kaons in the OKA facility.
