Combined measurements in low-energy electron diffraction of both intensity and electron spin polarization are described for Ni(1) and Ni(1)c(2x2)Te. Polarizations and intensities are determined in the energy ranges 2-1V and 25 to 2V, respectively. The beam has been measured at angles of incidence in the range 1° to 18° for azimuthal angles $ = ° and § = 45°. The 1/2 1/2 and 1 beams have been studied at normal incidence. Significant polarizations are observed, even for the low atomic number crystal Ni (1). Pronounced changes in the polarization profiles are induced by the addition of a tellurium overlayer.
