Spectroscopy of highly charged ions: New studies in the He, Be, N, O, Na and Mg isoelectronic sequences.
Spectroscopic investigations of highly charged ions have been performed in the VUV, UV and visible spectral regions using mainly the beam-foil technique. New 2s22px3l levels have been established in N and O-like Si and S, together with many transitions between these levels. Several of these lines have also been identified in the solar corona spectra recorded by the SUMER/SOHO instrument. In Mg-lik
