Long Wavelength Satellites to the He-like Ion Resonance Lines in the Laboratory and in the Sun

Nature volume 221, pages 947–949 (1969)Cite this article

Abstract

SATELLITE lines, situated on the long wavelength side of the He-like resonance lines in laboratory plasmas, are classified here as transitions in highly excited Li-like ions. We also show that intense features in the solar X-ray spectrum, of similar appearance, are of different origin, and these are classified as the forbidden ls2 1S0–ls2s 3S1 line of the He-like ion.
