The 4<i>d</i><sup>9</sup>-4<i>d</i><sup>8</sup>5<i>p</i> transition array of nine-times ionized xenon at 130-160Å was photographically observed with the National Bureau of Standards 10.7-m grazing-incidence vacuum spectrograph. The spectral source was a highvoltage 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 4<i>d</i><sup>8</sup>5<i>p</i> configuration to the two levels of the 4<i>d</i><sup>9</sup><sup>2</sup><i>D</i> 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.
