Spin dependent momentum distributions of proton-deuteron clusters in 3He from electron scattering on polarized 3He: Theoretical predictions

The process (subform(3He))-vector(e,e'p-vector)d [or (subform(3He))-vector sign(e,e'd-vector)p] is studied theoretically in a Faddeev treatment with the aim to have access to the spin dependent momentum distribution of p-vectord-vector clusters in polarized 3He. Final state interactions and meson exchange currents turn out to have a strong influence in the considered kinematical regime (below the pion threshold). This precludes direct access to the momentum distribution except for small deuteron momenta. Nevertheless, the results for the longitudinal and transverse response functions are interesting as they reflect our present day understanding of the reaction mechanism and therefore data would be very useful
