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 2s<sup>2</sup> 2p<sup>n</sup>-2s2p<sup>n+1</sup> and 2s 2p<sup>n+1</sup>-2p<sup>n+2</sup> transition arrays. Identifications include those of beryllium I-like 2s 2p-2p<sup>2</sup> spectra. The data is used to complete the tabulation of energy-level values for the 2s<sup>2</sup> 2p<sup>n</sup>, 2s 2p<sup>n+1</sup>, and 2p<sup>n+2</sup> configurations of these elements.
