Abstract

Resonance lines originating from autoionization energy levels far above the ionization potential have been observed for highly ionized atoms from Ti to Cu. Two of the lines for each ion have been classified as the transitions $2s^2\hspace{0.17em}2p^6\hspace{0.17em}3s\hspace{0.17em}²S_{\frac{1}{2}}-2s^2\hspace{0.17em}2p^5\hspace{0.17em}3s^2\hspace{0.17em}²{P^0}_{\frac{3}{2},\frac{1}{2}}$ of the Na i isoelectronic sequence. Wavelength and energy tables are given and a typical spectrogram is presented.
