VACUUM-ULTRAVIOLET SPECTRUM OF 6-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 Angstrom, and 27 new transitions have been identified as combinations between levels o f the 5p2-5p5d and 5s5d-5p5d transition arrays. From these transitions , 11 new levels have been determined. The energy-level assignments hav e been interpreted when the theoretical energy-level values were fitte d with a least-squares approach. Hartree-Fock calculations with relati vistic corrections were used to predict energy levels and transitions. (C) 1997 Optical Society of America.
