An. Ryabtsev et al., Analysis of the spectrum of the PdI-like xenon (Xe IX) and extended interpretation of the SbVI, TeVII and IVIII spectra, J PHYS IV, 11(PR2), 2001, pp. 317-319
The spectrum of Xe IX has been observed using a fast capillary discharge wi
th inductive storage as a light source and the normal incidence 6.65m spect
rograph at Troitsk, This follows extended observations of vacuum spark spec
tra of Sb VI, Te VII and I VIR at Troitsk and at Meudon. Theoretical studie
s of 4d(9)5l (l=s,p,d,f) configurations by means of the Cowan codes and by
generalized-least-squares fits along the Pd I sequence lead to classify 82
lines as 5-5 transitions of Xe IX.
