LEED spectra determination of the atomic location of tellurium adsorbed on Ni(001)

Abstract
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*2) overlayer structure rest in the four-fold coordinated bonding site at a distance of 1.90+or-0.1 AA away from the first nickel layer.
