Emission Line Spectra of Al IV-Al XI in the Extreme Ultraviolet Region 40-170 Å
Abstract
We measured wavelengths and intensities of L-shell emission lines of aluminum in the extreme ultraviolet wavelength band. We identify 75 features of Al IV through Al XI between 40 and 170 Å. The strongest features are due to 3 → 2 transitions; features from 4 → 2, 5 → 2, and 6 → 2 transitions are also included. Calculations made with the Flexible Atomic Code using the configuration-interaction method and many-body perturbation theory are presented and compared to the experimental results.
