Abstract

Spectra emitted from plasmas produced through focusing the output of a 4-GW neodymium-glass laser onto plane solid targets of potassium, calcium, scandium, titanium, and vanadium were recorded with a 2-m grazing incidence spectrograph as were argon spectra emitted from a theta-pinch plasma. The analysis of the spectrograms yielded line classifications for the 2s² 2pⁿ-2s2p^{n+ 1} and 2s 2p^{n+ 1}-2p^{n+ 2} transition arrays. Identifications include those of beryllium i-like 2s 2p-2p² spectra. The data is used to complete the tabulation of energy-level values for the 2s² 2pⁿ, 2s 2p^{n+ 1}, and 2p^{n+ 2} configurations of these elements.
