Popis:	Delbrück scattering, in which a gamma-ray interacting with a Coulomb field creates an electron-position pair, which subsequently annihilates to generate a gamma-ray which energy is almost identical with the incident gamma-ray, is one of important phenomena to study non-linear effects by QED and vacuum polarization. Koga and Hayakawa have presented that it is possible to measure selectively the amplitude of Delbrück scattering using linearly polarized gamma-ray beams. We have measured the scattered gamma-rays using1-MeVLCSgamma-rays, and calculated the expected spectrum using Geant4. Nuclear Photonics 2020
