Spin-polarization in LEED: A comparison of theoretical predictions

Two distinct theories of spin-dependent low energy electron diffraction have been used to calculate scattered intensities and polarizations for the same model of the W(001) surface. The agreement between the results is excellent, demonstrating that calculations using either program should provide a reliable basis for the analysis of experimentally measured intensities and polarizations. The effects of using different surface barriers and of increasing the number of phase shifts and diffracted beams are also examined.
