【 摘 要 】

Interference effects in the outer valence ionization cross sections have been theoretically investigated in simple hydrocarbons, and found comparable to those observed in core and inner valence ionizations. Notably short period oscillations give strong evidence of molecular orbital delocalization over the entire molecule. Also in the case of unresolved ionizations, interference patterns still survive in band ratios and convey useful information.
