Why on the Neutron?

◮ Isospin amplitudes of the elm. transitions depend on reactions

  • n proton and neutron

A(γp → π+n) = √ 2(A(0) + A(−)) A(γn → π−p) = √ 2(A(0) − A(−)) A(γp → π0p) = (A(+) + A(0)) A(γn → π0n) = (A(+) − A(0)) A(0) := isoscalar A(+), A(−) := isovector

◮ meson photoproduction from light nuclei, i.e. deuteron ◮ nuclear effects (rescattering of the mesons, FSI, ...)

Conclusions

Single π0 Photoproduction:

◮ Cross Sections for Single π0 in good agreement with former

results

◮ MAID/SAID overestimate the cross sections by 25% ◮ Reduction can not only be explained by Fermi motion

Double π0 Photoproduction:

◮ Same asymmetries for 2π0 on the proton as on the neutron ◮ Model predictions not yet in agreement with results, further

input needed

◮ Electromagnetic excitation of the resonances different for

proton and neutron. De-excitation of the resonances different for single and double pion production.
