Abstract

Photoelectron branching ratios and angular distributions have been measured for the six outermost levels of S $F_{6}$ in the range $16 \leq h ν \leq 30$ eV with the use of synchrotron radiation. These results are discussed in the framework of the large variety of experimental and theoretical studies of S $F_{6}$ with the dual objective of resolving the long-standing problem of the ordering of the valence shells and of gaining some insight into the role of shape-resonant behavior in the low-energy photoionization continua of S $F_{6}$ . These objectives are met with partial success in that we tentatively conclude the valence configuration $5 a_{1 g}^{2} 4 t_{1 u}^{6} 1 t_{2 g}^{6} 3 e_{g}^{4} (1 t_{2 u}^{6} + 5 t_{1 u}^{6}) 1 t_{1 g}^{6} {}^{1}A_{1 g}$ is most consistent with the available body of evidence and that it is plausible to invoke channel interaction near the strong resonant feature at $h ν \sim 23 - 24$ eV to help account for some of the apparently contradictory evidence. Further experimental and theoretical work is suggested to clarify these issues.
