C 1s photoelectron angular distributions from fixed-in-space CO molecules in the high-energy continuum ≥50 eV

Abstract

We measured molecular-frame photoelectron angular distributions (MFPADs) for a carbon 1s level of CO molecules in the kinetic energy range of up to 150 eV. X-ray photoelectron diffraction (XPD) theory was adopted to interpret the profiles of the MFPADs. Computational experiments within the framework of XPD theory were performed to demonstrate the emergence of interference effects between the direct photoelectron and scattered waves in the MFPAD profiles.
