Extended X‐ray absorption fine structures (EXAFS) of the L 3 ‐edges of dysprosium, holmium, thulium, ytterbium, and lutetium metals are investigated using a focussing X‐ray crystal spectrograph of transmission type. The present results are interpreted in the light of the EXAFS theories proposed by Hayasi and by Lytle and the interatomic distances in these metals are determined using Lytle's method. It is found that Moseley's law applies to the white lines in the lanthanides. A comparison of the widths of the white lines with the positron annihilation rates in lanthanides reveals interesting correlations.
