Abstract

Two different spectroscopy light sources are used to observe the spectrum of six-times-ionized argon, Ar vii, in the vacuum ultraviolet range, 300–1100 Å. Fifty-eight transitions are identified as combinations between levels of the 2p6(3s2+3p2+3s3d) and 2p6(3s3p+3p3d+3s4p) configurations. For 44 of these transitions the classification is new. Twenty-nine levels are determined that belong to these configurations, where 14 of these are new. The energy parameters are obtained with Hartree–Fock relativistic calculations. The energy levels of the configurations are interpreted by fitting the theoretical energy expressions to the experimental levels with the least-squares approach. Isoelectronic comparisons along the Mg i sequence are used to support the experimental results.
