Description
The method of coherent pi0 photo production (gamma + Ag.s.-> pi0 +Ag.s., where Ag.s. is a nucleus in its ground state) provides an ecient tool to study the neutron skin of various nuclei.
We will investigate the case of nuclei with zero spin and isospin from theoretical point of
view in the framework of a distorted wave impulse approximation in momentum space.
For the pion-nucleus nal-state interaction we will employ phenomenological pion-nucleus
optical potential, which involves analysis of pion-pion elastic scattering as the solution of a
Lippmann-Schwinger integral equation. As a rst application, we will show results for 12C.
