Figure 4
Main panel: PEPICO map of Arn+ ions in coincidence with the KLL Auger electrons, following 1s ionization by 4.9 keV photons. The top panel shows the coincident electron spectrum (solid line, `coel') and coincident ion yields for the Ar4+–Ar6+ ions (dots, `Arn+'). The curves are scaled differently to improve visibility. The right-hand panel shows the coincident ion spectrum, from which the false coincidences were subtracted. |
