Overlap of argon ion spectra with satellites to the Lyman-alpha lines of carbon and boron.

A theta pinch has been employed to investigate satellites to the H-like and He-like ion resonance lines of boron and carbon. Identification of the spectra shows an overlap of the Ar IX, Ar XI, and Ar XII lines with the predicted satellite wavelengths, and it is concluded that many of the previously reported satellite lines are due to argon impurities.
