Abstract: | The scattering and absorption differential cross sections for nonlinear QED process such as double photon Compton scattering
have been measured as a function of independent final photon energy. The incident gamma photons are of 0.662 MeV in energy
as produced by an 8 Ci137Cs radioactive source and thin aluminum foils are used as scatterer. The two simultaneously emitted photons in this process
are detected in coincidence using two Nal(T1) 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. |
