Wehave used an electron beam ion trap to observe avisible line at 598.30(13) nm that corresponds to the 4d⁹ ²D_3/2–4d⁹ ²D_5/2 magneticdipole transition within the ground state configuration of Xe⁹⁺. Wehave found no evidence to support the claim by othersthat a line near this position originates from Xe³¹⁺. Thecomparison of the measured wavelength with previous indirect experimental values,and the dependence of the line intensity on the electronbeam energy, confirms the validity of the present identification. Ourmeasured wavelength is in agreement with semiempirical Hartree-Fock calculations butshows a discrepancy with ab initio multiconfiguration Dirac-Fock calculations. Wepropose that the line may be useful as a diagnosticfor extreme ultraviolet lithography light sources.
