A new method for the determination of chemisorption site geometries using an angle-scanned forward scattering approach is proposed. The idea is based on the use of a heteroepitaxial monolayer deposited on a suitable single-crystal substrate as the source of the primary photoelectron wave. Preliminary single scattering cluster simulations performed on model systems show that the method might be successful with well-ordered adsorbates at high surface coverage, while it is of little use for low-coverage and/or disordered molecular overlayers. © 1995.

Abstract
A new method for the determination of chemisorption site geometries using an angle-scanned forward scattering approach is proposed. The idea is based on the use of a heteroepitaxial monolayer deposited on a suitable single-crystal substrate as the source of the primary photoelectron wave. Preliminary single scattering cluster simulations performed on model systems show that the method might be successful with well-ordered adsorbates at high surface coverage, while it is of little use for low-coverage and/or disordered molecular overlayers. © 1995.
