Dysprosium isotope structure

Figure 12. Isotope structure of the 5887.9-A line of neodymium (a) and the 5988.6-A line of dysprosium (b). The abscissa in each figure is relative frequency in gigahertz (11).

Figure 13. Structure of the 5988.562-A line of neutral dysprosium. Three of the lines—4,10 and 17—are due to even isotopes (no hfs), the remainder are hfs components from the odd 1 = 5/2 isotopes, dysprosium-161 and dysprosium-163. The key at the top gives the values for F(J = 8)...
