Presentation Possibilities to observe Delbrück scattering at next generation laser facilities

Kevin Koga, James  ,  Hayakawa, Takehito

We show by using high-flux linearly polarized laser Compton gamma-ray sources the contribution of the vacuum component, Delbrück scattering, to the elastic scattering of the gamma-rays off nuclei is nearly isolated for photon energies below the electron-positron pair creation threshold. We discuss the possibility of measuring Delbrück scattering at new ultra-high power laser and X-ray Free Electron Laser facilities.
