Abstract

The spectrum of five-times ionized aluminum was investigated in the 85–113 Å and 100–1500 Å wavelength regions. New energy levels were found in the 2s.<sup>2</sup>2p.<sup>3</sup>3s, 3p, and 3d configurations. Parametric calculations were made for the 2s.<sup>2</sup>2p.<sup>3</sup>3p configuration. They were also done for the interacting 2s2p.<sup>5</sup>, 2s.<sup>2</sup>2p.<sup>3</sup>3s, and 2s.<sup>2</sup>2p.<sup>3</sup>3d configurations in both Na IV and Al VI. The results are compared with similar calculations in Mg V.
