Abstract

The angular distributions of the vector analyzing power have been measured in the reactions $^{2}\mathrm{H}(p, p)np$ and $^{1}\mathrm{H}(d, p)np$ 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 $\mathrm{np}$ pairs with low relative energies, and the angular distributions show a remarkable similarity to those of the corresponding elastic scattering.
