Abstract

The spectrum of the copperlike ion Kr viii was observed with a low-inductance spark and 10.7-m normal- and grazing-incidence spectrographs. A total of 46 new lines with wavelengths ranging from 115 to 696 Å were identified: 18 of the type 3d¹⁰nl–3d¹⁰nl′, 10 of the type 3d¹⁰4s–3d⁹4s4p, and 18 of the type 3d¹⁰4p–3d⁹4p². From these lines 37 new energy levels were determined: 14 of the type 3d¹⁰nl, 10 belonging to 3d⁹4s4p, and 13 to 3d⁹4p². New values for all known levels were derived by combining the present results with measurements at longer wavelength by Gallardo et al. [ Appl. Opt. 28, 5088 ( 1989)]. The ionization energy was found to be 1014665 ± 25 cm⁻¹ (125.802 ± 0.003 eV). New wavelength measurements were made for the 3d¹⁰–3d⁹4p, 4f resonance lines of the nickellike ion Kr ix.
