THE ANGULAR-DISTRIBUTIONS OF 1S PHOTOELECTRONS FROM SPATIALLY ALIGNEDCO USING ANGLE-RESOLVED PEPICO

Results are presented for the angular distributions of electrons from spatially aligned core excited CO using an angle-resolved photoelectro n-photoion coincidence technique in the regions of the C and O 1s edge s and sigma resonances. Coincidence measurements were recorded betwee n ions ejected at 0 degrees and 90 degrees with respect to the electri c field of the linearly polarized radiation and for photoelectrons ran ging from 0 degrees to 90 degrees with respect to the molecular axis. The results show a strong departure from angular distribution measurem ents made more conventionally; in particular, multiple outgoing partia l waves of high angular momentum are seen to make a significant contri bution.
