The expressions of the matrix elements of the electron spin–spin contact interaction have been tabulated for all the states arising from fn configurations. Numerical calculations have been carried out for a large number of lanthanide atoms and ions using accurate numerical Hartree–Fock functions.

Isoelectronic Series

The values of the total electron spin–spin contact interaction and the mass-variation and Darwin relativistic corrections have been calculated for a number of isoelectronic series. It is observed that the main contributions to these corrections, that are not negligible, are made by the inner electrons.

The total electron spin–spin contact interaction, including both the inter and intrashell contributions, has been evaluated from existing numerical Hartree–Fock functions, for the ground states of the neutral atoms and doubly and triply charged positive ions from La to Yb.
