The ratio 3〈T〉z/〈S〉z between the expectation values of the magnetic dipole and the spin operators along the quantization direction as a function of the 5f occupation number nf. Symbols are experimental data obtained from an analysis of XMCD spectra at the M4,5 actinide edges for compounds with different physical properties and crystallographic structure (circles for C-15 cubic Laves phases, squares for orthorhombic structures, down triangles for NaCl-type structure, and up triangles for hexagonal lattice groups). Theoretical estimates are shown for intermediate coupling (IC) (solid lines), Russell–Saunders (LS) (dashed line), and j–j (dotted line) coupling approximations.
