If a beam of unpolarized nucleons is scattered from a target of unpolarized nucleons, the scattered particles are polarized (in a direction normal to the scattering plane) provided that the interaction contains tensor or spin-orbit forces. The polarization can be detected by means of a second similar scattering since the cross section then contains an azimuthal dependence: $I(\ensuremath{\theta}, \ensuremath{\varphi})={I}_{0}(\ensuremath{\theta})(1+\ensuremath{\epsilon}cos\ensuremath{\varphi}),$ where $\ensuremath{\epsilon}(\ensuremath{\theta})$ is essentially the square of the polarization. Calculations are carried out by the author for a double $p\ensuremath{-}p$ scattering using the tensor interaction described in the preceding paper, and for a double $n\ensuremath{-}p$ scattering using the central and tensor potential of Christian and Hart (containing the "half-exchange" dependence proposed by Serber). The polarization produced by the first scattering at the optimum angle of $\ensuremath{\theta}\ensuremath{\approx}50\ifmmode^\circ\else\textdegree\fi{}$ was found to vary from 6 percent at 40 Mev to 33 percent at 285 Mev for $n\ensuremath{-}p$ scattering and from 10 percent 129 Mev to 15 percent at 350 Mev for $p\ensuremath{-}p$ scattering. The $n\ensuremath{-}p$ results (previously published) are consistent with the azimuthal asymmetry detected in a double scattering experiment reported by L. Wouters.
