Abstract
AN examination of hyperfine structure in the visible lines of the Ga II spectrum with a Fabry-Perot interferometer has shown the patterns due the individual isotopes to be distinctly separated by a difference in the magnetic moments of the nuclei. This permits the mechanical moments to be separately determined as i = 3/2 for both isotopes, in accord with previous determinations from incompletely resolved structures in Ga I lines1 and Ga II lines2. The ratio of the g(i) factors, given by the relative magnitudes of the hyperfine term separations, is 1.27, the less abundant isotope 71 having the larger magnetic moment.
