Abstract
Spectra of aluminum and magnesium emitted from a Penning ionization discharge have been recorded in the XUV range by 2-m grazing-incidence spectrometer. Autoionizing satellite lines, originating from transitions between core excited levels lying in the continuum and ground or lowest excited states of the Na I-like Al III and Mg II, have been classified. Their implication for ionization cross-section estimates and XUV laser research is discussed.Keywords
