Abstract
We calculate the two-dimensional energy bands of a 35-layer (100) Ni film. Surface states exist above the majority-spin bands throughout the two-dimensional Brillouin zone. Transitions from these surface states into an evanescent LEED (low-energy electron-diffraction) state account for the reversal of photoelectron spin polarization observed 0.1 eV above threshold.
