Calculated photoionization cross sections for SF6

We have calculated the photoionization cross sections for the valence levels of S${\mathrm{F}}_6$,using multiple-scattering $X\alpha$ methods for both the initial and final states. The theoretical curves are compared with measured cross sections in an attempt to complete the identification of observed photoionization peaks with theoretically predicted valence levels. We find general agreement between theory and experiment, although one notable difficulty remains.
