Abstract
K x rays have been observed in low energy collisions of bare Kr, Ar, and Ne ions with a neutral gas target.Although largely neglected previously, we have found that multiple-electron transfer processes play a signifi-cant role in shaping the x-ray spectra. The observed ratios of normal-satellite to hyper-satellite line intensitiesare found to be roughly independent of the ion species and much larger than those estimated from previouslyreported electron transfer cross sections, suggesting that there may be a strong correlation between two electronsduring the electron transfer or during the subsequent cascades. It is suggested that exact knowledge of theinitial and final principal and angular momentum quantum numbers n, l in electron transfer are the mostessential missing ingredients for understanding the entire x-ray emission process in astrophysical, laboratory,and technological plasmas.Citation
