The Chase's adiabatic approximation and Schwinger variational technique in static-exchange approximation are applied to investigate the effect of vibrational averaging on the shape resonant photoionization leading to the A2T1u state of SF6+. For this study, two of the S-F stretching vibrations are considered: the 1 symmetric stretching mode and the two degenerate 2 asymmetric stretching modes. Present work concludes that averaging over the asymmetric stretching mode of vibration reduces the peak eg resonant cross section by 45% relative to the results obtained at the equilibrium nuclear configuration, which agrees with experimental observation. However, the eg shape resonance is not affected significantly by averaging over the 1 symmetric stretching mode of vibration.
