Measurements were made of the polarization ratio of the scattered intensities for the two neutron spin states for two reflections (110) and (220) for positive angles and for the reflection (110) at negative angles. Very high neutron polarization was available and the intensity was studied as the magnetic field on the crystal was reduced to zero so as to avoid any electronic polarization scattering. Crystals of vanadium, silicon, and sodium chloride were used. (C.E.S.)
