The polarization and differential cross sections for neutrons scattered from Zr, Nb, Mo, and Cd were measured at five angles for neutron energies between 0.275 and 0.85 Mev. The results were analyzed in terms of a local optical model equivalent to the noniocal model of Perey. The analysis leads to the following major conclusions; the calculations, corrected for the effects of compound elastic scattering, are consistent with most of the observed scattering data, particularly when a spin-orbit potential that includes both a real and imaginary term of the Thomas type is employed; and calculations (based on this model) of the magnitude and shape of the P-wave neutron strength function in the region near A = 100 are not very sensitive to the parameters of the spin-orbit potential -- at least when the real term is between 7 and 2 Mev and the imaginary term is between 0 and 7 Mev.
