Abstract

Spectra of highly charged Mo ions generated in a laser-produced plasma were observed from 10 to 190 Å with a 3 m grazing- incidence spectrograph. Line identifications in MoXXX– XXXII were made with the help of relativistic Hartree-Fock calculations. In MoXXXI (Mg-like) the 3<i>s</i><sup>2</sup><sup>1</sup><i>S</i><sub>0</sub>–3<i>s</i> 3<i>p</i><sup>1</sup><i>P</i><sub>1</sub>, resonance line was found to be at 115.944 Å. In MoXXXII (Na-like) the 3<i>s</i><sup>2</sup><i>S</i><sub>½</sub>–3<i>p</i><sup>2</sup><i>P</i><sub>3/2, ½</sub>, resonance lines are at 127.814 and 176.62 Å These values support the recent identifications of these lines in the Princeton ST tokamak by Hinnov. The density-sensitive 3<i>p</i><sup>2</sup><i>P</i><sub>3/2</sub>–3<i>d</i><sup>2</sup><i>D</i><sub>5/2</sub> transition in MoXXXII is at 126.937 Å. At shorter wavelengths, the 3<i>s</i>–4<i>p</i> transitions of MoXXXII are at 14.384 and 14.565 Å.
