Keywords:laser Compton scattering gamma-rays, Delbruck scattering

Delbruck scattering which is one of elastic scattering of gamma-rays on atoms has been studied for verification of QED from 20th century. It has been practically impossible to measure only the cross section of the Delbruck scattering. Recently, Koga and Hayakawa presented the calculated result that it is possible to measure only the amplitude of the Delbruck scattering with linearly polarized gamma-rays. We present the detail of the calculation and the generation of laser Compton scattering gamma-rays at UVSOR to study the Delbruck scattering.
