摘要: Abstract In order to study the effects of photon-polarization selection rules on chemisorptionbond geometry, we have measured photoelectron spectra as a function angle incidence, θ i , in range 28° ⩽ 80°. A noble-gas UV resonance lamp and cylindrical mirror analyzer were used measure both bonding non-bonding surface Orbitals. large enhancement (200–400%) photocmission is found when photon electric field intensity near maximum normal surface. This indicates spatial variation microscopic fields which approximately independent adsorbate since it determined by optical properties substrate. addition, observe some peaks due different orbital symmetry. The case atomic hydrogen chemisorption discussed an example this latter effect.
