Deuteron Compton Scattering Above Pion Threshold

Results are reported of the first experimental measurement of deuteron Compton scattering cross sections at photon energies above pion threshold. The measurements are not precise enough to provide a meaningful extraction of the electromagnetic polarizabilities. However, this experiment demonstrates that measurements above pion threshold are feasible. As a results, future versions of this measurement could be used to improve the current state of deuteron Compton scattering data set and the extracted neutron polarizabilities.
