Vacuum ultraviolet spectrum of six-times ionized xenon, Xe VII

The theta-pinch spectrum of six-times ionized xenon, Xe vii, has been recorded in the vacuum ultraviolet region of 300–1300 Å, and 27 new transitions have been identified as combinations between levels of the 5p2–5p5d and 5s5d–5p5d transition arrays. From these transitions, 11 new levels have been determined. The energy-level assignments have been interpreted when the theoretical energy-level values were fitted with a least-squares approach. Hartree–Fock calculations with relativistic corrections were used to predict energy levels and transitions.
