Temperature effects in polarized low‐energy electron scattering from solids and liquids

W. N. Unertl

National Bureau of Standards, Washington, D.C. 20234

The effects of temperature on the polarization of low‐energy electrons scattered from surfaces of liquids, polycrystals, and single crystals are discussed. The polarization of the single scattering component of the intensity is shown to be independent of temperature, whereas that of the multiple scattering intensity is temperature dependent. Differences between polarizations observed for electron scattering from free atoms and from polycrystals and liquids are qualitatively explained and a quantitative theory is outlined. The implications for polarized low‐energy electron diffraction from single‐crystal surfaces are also discussed.
