Leed spectra determination of the atomic location of tellurium adsorbed on ni001

The close agreement between experiment and calculated elastic low-energy electron diffraction spectra for both fractional- and integral-order beams leads to the conclusion that Te atoms adsorbed on Ni(001) as a c(2 x 2) overlayer structure rest in the four-fold coordinated bonding site at a distance of 1 -90 ± 0T Â away from the first nickel layer. © 1973 IOP Publishing Ltd.
