Dirac-Fock studies of some electronic properties of rare-earth ions

This paper reports results of accurate fully relativistic Dirac-Fock studies of some electronic properties of rare-earth ions. We present, in addition to eigenvalue information including spin-orbit splittings (useful for interpreting ESCA experiments), 〈rⁿ〉 values (for n = -3, 2, 4, 6) for the 4f electrons and Slater F^k and G^k integrals (of interest for hyperfine interaction and crystal field descriptions), values of the Mössbauer isomer shift electronic densities and the 〈j_i〉 integrals useful for interpreting neutron magnetic form factor measurements.
