All experimental data on Ne VII, including previously unpublished beam-foil spectroscopy data, have been compiled and critically evaluated. More than a hundred spectral lines have been newly identified. For 40 transitions, the previous identifications have been revised. These revisions resolved all existing contradictions between previously published interpretations of the spectrum. An optimized level scheme has been derived from the total list of observed lines. About a hundred new energy levels have been found, including several highly excited hydrogenic levels. Based on these newly determined levels, as well as on the analysis of theoretical data, the ionization potential has been newly determined with improved confidence.
PACS: 32.10.Fn – Fine and hyperfine structure / 32.10.Hq – Ionization potentials, electron affinities / 32.30.Jc – Visible and ultraviolet spectra / 31.15.Ct – Semi-empirical and empirical calculations (differential overlap, Hückel, PPP methods, etc.)
