TL;DR: In this article, the position and chemisorption energy of O on Ni(100) as a function of coverage and including atomic relaxations were studied. But the results do not indicate the pseudo-bridge position as a stable one.
Abstract: We study the position and chemisorption energy of O on Ni(100) as a function of coverage and including atomic relaxations. A Hubbard like tight-binding Hamiltonian and the Hartree-Fock approximation is used. The repulsive interaction between atoms is described by a Born-Mayer type potential. Results are given for atomic relaxations and for the binding energy of O at various chemisorption sites. Our results do not indicate the pseudo-bridge position as a stable one.

TL;DR: In this paper, a detailed LEED analysis of the p(2 × 2)O/Ni(100) phase was conducted, whereby the purity of the 2 × 2 phase was controlled by HREELS.
