Abstract

Abstract A one-dimensional multiple scattering model is used to construct a model for normal photoelectron diffraction (NPD). The model which is an extension of earlier work on NPD and which we recently applied to LEED with some success, proves successful in interpreting experimental NPD data of Se(3d), S(2p) and O(1s) on Ni(001). The model can be used to rapidly estimate NPD structural parameters such as d from experimental data. In addition, we exhibit NPD spectra for the fictitious adsorbate Ni(001)Ni and Cu(001)Cu systems. When these spectra masquerade as LEED spectra, they exhibit the observed secondary peaks absent in the simple one-dimensional calculated LEED spectra but present experimentally. This calculation complements our previous work showing how the normal geometry LEED data on Ni(001) and Cu(001) can be described in a one-dimensional model.
