• The scattering and absorption differential cross sections for non-linear QED process such as double photon Compton scattering have been measured as a function of scattering angle θ1, when one of the emitted photon's having energy in the range 50-100 keV is detected at θ_2 = φ_2 = π/2. The incident gamma photons are of 0.662 MeV in energy as produced by an 8 Ci ^<137>Cs radioactive source and thin aluminum foils are used as scatterer. The two simultaneously emitted photons resulting from the interaction of incident photons with electron of aluminum target are detected in coincidence using two NaI(Tl) scintillation detectors and a slow-fast coincidence set-up of 30 nsec resolving time. The measured values of scattering and absorption differential cross sections agree with theory within experimental estimated error of nearly 22%.
