Abstract

To investigate the interactions of ⁵⁷Fe atoms with sulfur hexafluoride SF₆ molecules, in-beam Mössbauer spectra were measured for ⁵⁷Mn implanted SF₆ at 9 K and 65 K. Isolated ⁵⁷Fe atoms or ions produced by β-decay were not trapped within the SF₆ matrix. At 9 K, monomeric FeF₂ and FeF₃ molecules were produced by reaction of ⁵⁷Fe with F atoms released by decomposition of the SF₆ molecules. When the temperature of the SF₆ solid was increased to 65 K, FeF₄ was formed in addition to FeF₂ and FeF₃. Density functional calculations were performed to confirm the assignments of the candidate species identified in the Mössbauer spectra.
