Abstract:

Polarization correlation coefficients have been measured at RIKEN for the \vec³ He(\vecd,p)⁴ He reaction at intermediate energies (E_d = 270 MeV). We propose a model for the (\vecd, p) reaction mechanism using the pd elastic scattering amplitude, which is rigorously determined with a Faddeev calculation and using modern NN forces. Our theoretical predictions for the deuteron polarization observables A_y, A_yy, A_xx and A_xz at E_d = 140, 200 and 270 MeV are given. The A_y observables agree qualitatively in shape with the new experimental data for the reaction ³ He(\vecd,p)⁴ He.
