An elastic scattering experiment has been performed using 100% linearly polarized gamma-rays generated by laser Compton backscattering at Duke University, NC, USA. Photons of energy of 2 MeV elastically scattered off uranium target were measured with high-purity Ge detectors. The results are used in the simulation study to improve the sensitivity of identifying isotopes by nuclear resonance fluorescence. Validation of the elastic scattering cross section of a polarized gamma-rays is reported.
