Abstract

The spectrum of Mo from 20 to 90 Å was obtained with a laser-produced plasma and a low-inductance vacuum spark. Wavelengths and line identifications were determined for transitions of the type 3d–4p and 3d–4f in Mo xiii–xvi and for 3p–3d type transitions in Mo xvi–xviii. The line identifications were obtained with the aid of relativistically corrected Hartree-Fock calculations. Energy-level diagrams are given for the 3d⁸4p and 3d⁸4f configurations of Mo xvi.
