Employing the 64% polarized neutron source from the T(dn)He/sup 4/ reaction at 30 deg for an incident deuteron energy of 7.7 Mev, the angular dependence of the polarization for elastic scattering of 24-Mev neutrons from C, Al, Fe, Sn, and Bi has been measured from 20 to 70 deg in 5 deg steps. The left'' and right'' measurements are obtained by precessing the neutron spin magnetic moment plus and minus 90 deg with a suitably designed solenoid. The measured polarizations are in reasonable agreement with the opticalmodel predictions of Bjorklund and Fernbach, provided that the sign of the spin-orbit potential agrees with that deduced from the shell model. The magnitude of the spin-orbit potential (25 times Thomas) is in agreement with that deduced from fitting the proton polarization data. (auth)
