low energy electron diffraction (LEED)

Any technique which measures the angular intensity distribution of electrons reflected from a crystalline surface under bombardment with low energy electrons (\(E_{0} < 500\ \text{eV}\)) in larger angles of incidence. The @D01711@ pattern also provides very surface sensitive information on the atomic arrangement of the top layers of a solid.
