Modified form factors from multiconfiguration Dirac-Fock wave functions for neutral atoms with Z = 70-100.
Tables of modified X-ray scattering factors for neutral elements with Z = 70-100 have been calculated using multiconfiguration Dirac-Fock wave functions. The physical approximation is a next step beyond the usual form-factor approximation in calculating elastic scattering photon intensities. Differences as large as 3-6% compared to previous calculations of the same kind are obtained; differences from the usual form factors are much larger.
