Abstract

THIS REPORT DESCRIBES A STUDY OF UNOCCUPIED ADSORBATE-INDUCED ELECTRONIC BANDS ON NI. SPECTRAL FEATURES ARE IDENTIFIED WHICH, DUE TO THEIR DISPERSION WITH THE PERPENDICULAR WAVE VECTOR, CANNOT BE ASSIGNED TO NEW ELECTRONIC STATES OF THE CHEMISORPTION SYSTEM. COMPARISONS WITH S AND CL ADSORPTION EXHIBITING THE SAME GEOMETRICAL OVERLAYER STRUCTURE RESULT IN IDENTICAL FEATURES IN THE IPE SPECTRA. THE ABSENCE OF THIS EXTRA EMISSION ON THE 0-P (2X1) - NI (110) SYSTEM AS WELL AS THE OBSERVED DISPERSION BEHAVIOUR LEADS TO THE FIRST CONCLUSIVE IDENTIFICATION OF SURFACE UMKLAPP IN INVERSE PHOTOEMISSION.
