Identification of the SiF6 2- dianion by accelerator mass spectrometry and a fully relativistic computation of its photodetachment spectrum
The small doubly-charged molecular anion SiF6 2- was studied by two distinct approaches, one experimental the other theoretical. The dianion was produced in the gas phase by sputtering a Li2 SiF6 specimen with Cs+ ions and was detected by means of accelerator mass spectrometry. The identification was via the Si29 F6 2- 19 isotopomer; it has an odd total mass and therefore the dianion shows up at a half-integral mass-to-charge ratio (M q=71.5 amu) in the mass spectrum, facilitating a positive...[Show more]
