TL;DR
This paper reports measurements of Delbrück scattering cross sections at photon energies between 140 and 450 MeV, showing good agreement with theoretical predictions in a Coulomb field.
Contribution
First experimental measurement of Delbrück scattering cross sections in the 140-450 MeV range on a bismuth germanate target, confirming theoretical models.
Findings
Measured differential cross sections at specified energies and angles.
Observed strong agreement with Coulomb field theoretical calculations.
Validated theoretical models for high-energy Delbrück scattering.
Abstract
The differential cross section of Delbr\"{u}ck scattering is measured on a bismuth germanate target at photon energies and scattering angles . A good agreement with the theoretical results, obtained exactly in a Coulomb field, is found.
