Jar. Samson et al., AUTOIONIZATION OF DOUBLY-EXCITED AR ATOMS INTO AR2+ AND AR+ CONTINUUMSTATES, Journal of electron spectroscopy and related phenomena, 66(1-2), 1993, pp. 75-81
Numerous doubly excited neutral states of Ar have been observed by the
use of photofluorescent and photoion spectrometry. These states are o
bserved to autoionize into Ar+ satellite states and into the Ar2+ cont
inuum. Doubly excited Rydberg states with the configuration (3s3p(5))n
l,n'l' are observed above the Ar2+ threshold. Possible decay pathways
of these states are discussed.
