Abstract

The 4d9–4d85p transition array of nine-times ionized xenon at 130–160 Å was photographically observed with the National Bureau of Standards 10.7-m grazing-incidence vacuum spectrograph. The spectral source was a high-voltage spark between carbon electrodes triggered by insertion of a small quantity of xenon. Forty-seven lines were classified as transitions from 34 levels of the 4d85p configuration to the two levels of the 4d9 2D ground term. An excellent correlation was found between the observed and calculated relative intensities. Least-squares-fitted parameter values and their ratios to the Hartree–Fock values are given.
