Experimental study of the 3He(γ, pp)n reaction with polarized photons

The experimental study of the reaction 3He(γ, pp)n is being carried out in the photon energy range Eγ = 200–500 MeV at the Tokyo 1.3 GeV electron synchrotron. By use of the tagged and linearly polarized photon beam, and the π-sr magnetic spectrometer TAGX, a kinematically complete measurement of the reaction 3He(γ, pp)n will be made. The high statistics measurements of dσdΩ and Σ of the reaction 3He(γ, pp)n will clarify the photon absorption mechanism.
