Reaction mechanism and characteristics of [Formula Presented] in [Formula Presented] backward elastic scattering at intermediate energies

For backward elastic scattering of deuterons by [Formula Presented] cross sections [Formula Presented] and tensor analyzing power [Formula Presented] are measured at [Formula Presented] MeV. The data are analyzed by the plane wave impluse approximation (PWIA) and by the general formula which includes virtual excitations of other channels, with the assumption of the proton transfer from [Formula Presented] to the deuteron. Using [Formula Presented] wave functions calculated by the Faddeev equation, the PWIA describes global features of the experimental data, while the virtual excitation effects are important for quantitative fits to the [Formula Presented] data. Theoretical predictions on [Formula Presented] (polarization transfer coefficient), and [Formula Presented] (spin correlation coefficient) are provided up to GeV energies.
