Abstract: | The shifts of the Kα
1 and Kβ
1 lines of all rare-earth (RE) metals (from La to Lu) have been measured experimentally by the x-ray shift method. The population
of the RE-metal 6s and 5d shells has been determined by comparing the experimental and theoretical shifts obtained within the Dirac-Fock (Koopmans)
model. Trivalent metals exhibit a monotonic cross-over from the 6s
≈25d
≈1 to 6s
≈15d
≈2 configuration with increasing atomic number.
