Vector and Tensor Analyzing Power Measurements in the Scattering of Polarized Deuterons by Protons and Comparison with Exact Three-Body Calculations

Abstract

Vector $i{T}_{11}$ and tensor $Q=\left(\frac{1}{2\sqrt{2}}\right)(T_{20}+\sqrt{6}{T}_{22})$ and $R=\left(\frac{1}{2\sqrt{2}}\right)(T_{20}-\sqrt{6}{T}_{22})$ analyzing powers have been measured in the elastic scattering of 20.4-, 25.2-, and 29.9-MeV polarized deuterons by protons. Comparison is made with Faddeev-equation calculations including spin-dependent nucleon-nucleon interactions. Qualitative agreement is obtained for all the measured quantities only when both the spin-dependent nucleon-nucleon $P$-wave forces and the tensor (${}_{}{}^3{}_{}{}^{}S_1^{}{}_{}{}^{}-{}_{}{}^3{}_{}{}^{}D_1^{}{}_{}{}^{}$) force are taken into account.
