Abstract

The spectrum of Mg<sup>4+</sup> was observed between 95 and 400 Å. New wavelengths result in revised-energy level values and some resolved term structure. Parametric calculations with configuration interaction were made for the 2s2p<sup>5</sup>, 2s<sup>2</sup>2p<sup>3</sup>3s, and 2s<sup>2</sup>2p<sup>3</sup>3d configurations. These support rejection of some levels and some new identifications.
