Abstract

Angular resolved autoionization spectra after core to bound excitation of N₂ adsorbed on Ni(110) are presented. The experimental autoionization spectra are compared with calculated spectra for the model system Ni-N-N by application of the many-body Green's function technique using SCF-MO-CNDO one particle wavefunctions. The angular dependences of the autoionization lines are explicitly calculated. The theoretical approach allows one to assign the spectra obtained after core to bound excitation including angular effects within the framework of molecular orbital theory. The assignment is compared with results for the CO on Ni(110) system.
