Multicharged Kr ions have been measured using monochromatized undulator radiation combined with a coincidence technique. It has been found that a charge-state distribution of Kr ions being coincident with satellite peaks of Kr 2p{sub 3/2} photoelectron is slightly different from that for the main line. Resonant Auger peaks for 2p{sup -1}nl{yields}{sup 1}G{sub 4} nl transitions generated essentially Kr{sup 4+} only, which differs from the charge-state distribution for the normal Auger peak. These findings suggest that loosely bound electrons in high Rydberg orbitals are easily shaken-off in electron emission processes.
