Fig. 37—FINE STRUCTURE OF SPECTRAL LINES IN THE EXTREME ULTRA-VIOLET
The photograph shows the character of the resolution obtained in the recent study by Bowen and Millikan of the fine structure of spectral lines in the extreme ultra-violet. The seven lines in brackets on the left are components of the 834.0 oxygen line. Their total separation is but about two angstroms. The bracketed doublet on the right is one of the many studied, the separation of which is predicted by the theoretical-relativity-doublet formula.
