We report calculated cross sections and asymmetry parameters for photoionization out of the outermost valence orbital 2 b 2 u of C 2 F 4 for photon energies ranging from near‐threshold to 19 eV. We also report asymmetry parameters for photoionization out of the eight outermost orbitals of C 2 F 4 at the He I radiation energy (21.23 eV). The iterative Schwinger variational method at the exact static‐exchange level is used to obtain the continuum photoelectron orbitals. Our calculated results are compared with experimental results available in the literature. © 2006 Wiley Periodicals, Inc. Int J Quantum Chem, 2006
