The production and subsequent autoionization of the Ar+(D-1(2))6d' sat
ellite state that is formed either by shake-up or recapture during the
Auger decay of a 2p vacancy in Ar has been studied by photoelectron s
pectroscopy in the energy region from 243 to 256 eV. The creation of n
ear zero energy electrons below and immediately above the Ar 2p ioniza
tion threshold is discussed. Some ambiguous points in previous studies
are clarified. [S1050-2947(98)12609-4].
