Abstract

Molecular bromine dissociatively adsorbs to form a chemisorbed overlayer on Ni(100). The bromine induced 4p_x,y and 4p_z orbitals have been identified at Γ̅ with binding energies of 6.6 ± 0.2 eV and 5.3 ± 0.2 eV below the Fermi energy, respectively. The relative ionization cross-section variations of the two bromine levels 4p_x and 4p_z are observed to differ with changing photon energy.
