Theoretical analysis of the extraction of neutron skin thickness from coherent π⁰ photoproduction off nuclei

NUCLEAR REACTIONS ¹²C, ⁴⁰Ca, ¹¹⁶Sn, ¹²⁴Sn, ²⁰⁸Pb(γ, π⁰), E=200 MeV; calculated σ(θ). Plane-wave (PWIA) and distorted-wave (DWIA) impulse approximation using the density profiles obtained with Sao Paulo parametrization and the prediction of the FSU relativistic mean-field model. Comparison to experimental data. Concluded that photoproduction of a neutral pion on a nucleus is largely insensitive to the nuclear density and thus is not a good tool for neutron skin thickness study.
