Abstract

The spectrum of ten-times ionized xenon Xe XI was observed in the region 105 Angstrom} to 157 Angstrom} with a low-inductance vacuum spark and a 10.7 m grazing-incidence spectrograph. About 200 lines belonging to the 4p⁶4d⁸-(4d⁷5p+4d⁷4f+4p⁵4d⁹) transition array were observed. Of these lines, 140 are in the Region 130 Angstrom} to 140 Angstrom}, which is of importance for extreme ultraviolet (EUV) projection lithography. The spectrum was interpreted by means of Hartree-Fock calculations and orthogonal parameters using scaling factors for the energy parameters obtained by extrapolation along the Rh II isoelectronic sequence. All 9 levels of the 4d⁸ configuration and 123 levels of the 4d⁷5p+4d⁷4f+4p⁵4d⁹ configurations were established. Transition probabilities for all observed lines were calculated with fitted values of the energy parameters.
