We use the polyatomic Schwinger variational method with Padé corrections to calculate the cross section and asymmetry parameter for the sulfur 1s core level photoionization of SF6, for photon energies from threshold up to 2600 eV. Our results show very good agreement with experimental cross sections. Our asymmetry parameter show good qualitative agreement with experiment. A resonant feature at a photon energy of ≈2550 eV is found to be due to a nonvalence type resonant state which is trapped by an l=9 angular momentum barrier.
