Although SF/sub 6//sup -/ is known to be the major negative charge carrier initially produced by electron attachment, the subsequent ion chemistry of SF/sub 6/ corona is not completely established. Recent efforts to model the yield of the neutral by-product SOF/sub 4/ in SF/sub 6/ corona suggest that reactions of SF/sub 6//sup -/ with SOF/sub 4/ can be an important factor on the model. Reactions of SF/sub 6//sup -/, with various species that are either present initially in the gas or are produced by the corona and allowed to accumulate, result in the formation of stable product ions. To this end, negative ions produced by corona discharges in SF/sub 6/ have been studied by mass spectrometry in the pressure range 1.6-20 kPa (12-150 torr). 9 refs., 5 figs., 2 tabs.
