Polarization effects in the final-state interaction region of the p--d breakup reaction

The angular distributions of the vector analyzing power have been measured in the reactions $sup 2$H(p,p) np and $sup 1$H(d,p) np at 22.7 and 45.4 MeV, respectively, corresponding to the same center-of-mass energy. Significant analyzing powers were found in the production of final-state np pairs with low relative energies, and the angular distributions show a remarkable similarity to those of the corresponding elastic scattering.
