2020WI02 Phys.Rev. C 101, 024003 (2020) H.Witala, J.Golak, R.Skibinski, K.Topolnicki, V.Urbanevych Investigation of the interaction of circularly and linearly polarized photon beams with a polarized 3He target NUCLEAR REACTIONS 3He(polarized γ, p)d, (polarized γ, p)np, (polarized γ, 2p)n, E=15, 30 MeV; calculated σ(E), analyzing powers, spin correlation coefficients for the two-body and the three-body photodisintegration of polarized 3He target using three-nucleon Faddeev equations, and semi-phenomenological AV18 nucleon-nucleon potential combined with the Urbana IX three-nucleon force. Discussed several kinematically complete configurations, symmetric space-star (SST) and final-state interactions (FSI). Relevance to new generation of precise experiments on 3He photodisintegration.
