Wolfenstein polarization observables for the reactionppolp→ppolπnat 800 MeV

The Wolfenstein polarization observables $D_{\mathrm{NN}}$, $D_{S\Omega }$, and $D_{L\Omega }$, where Ω denotes a mixture of S and L polarization components, and the induced polarization P have been measured for the reaction pp→p${\pi }^{+}$n at 800 MeV, at geometries corresponding to ${\Delta }^{++}$ production from ∼10° to 80° in the center of mass. Comparisons are made to results from the model of Dubach, Kloet, and Silbar.
