Abstract

The spectrum of nine-times ionized krypton, Kr x, was observed with a low-inductance vacuum spark and a 10.7-m grazing-incidence spectrograph. Forty-four spectral lines in the region 91–105 Å were classified as 3p⁶3d⁹–3p⁵3d¹⁰ and 3p⁶3d⁹–3p⁶3d⁸4p transitions. The identifications were made with the aid of Hartree–Fock and least-squares parametric calculations.
