Coherent Scattering of 1.33 MeV. γ-Rays by Lead

THE cross-section for coherent (elastic) scattering of γ-rays from a heavy atom is expected to include a contribution from Delbrück scattering, the scattering of light by a static electric field 1 . This contribution should appear as a deviation of the experimental cross-section from the cross-secti...

Zusammenfassung:THE cross-section for coherent (elastic) scattering of γ-rays from a heavy atom is expected to include a contribution from Delbrück scattering, the scattering of light by a static electric field 1 . This contribution should appear as a deviation of the experimental cross-section from the cross-section calculated taking only Rayleigh scattering and nuclear Thomson scattering into account; but uncertainties in both theory and experiment have made it difficult to draw any definite conclusions from the results at low energies 2,3 .
