Hartree–Fock atomic scattering factors for the iron transition series

Abstract

Atomic scattering factors for thirty-five atoms and ions of the iron group transition series (Sc through Cu) were determined from Watson's calculation of Hartree-Fock wave functions and compared with previous calculations. Principal scattering factors were computed, following the methods of Freeman, for the 3d electrons of those atoms containing nonspherical charge distributions. As was shown by Weiss and Freennan, these factors are all that are needed for determining (from the measured neutron form factor) the spatial symmetry of the outer electrons in magnetic materials. Argon core scattering factors were calculated, and, on the basis of these new results, the question of the constancy of the argon core is discussed quantitutively. (auth)
