On the Influence of the Packing on the Atomic Scattering Factor Based on the Thomas-Fermi Theory

Abstract

The influence of the juxtaposition in the crystal on the atomic scattering factor has been investigated on the basis of the Thomas-Fermi(abbreviated as TF) theory, using the TF functions appropriate to the packed neutral atoms. It is pronounced especially for the smaller values of sin θ/λ· Z -1/3 . The values of the atomic scattering factor for free neutral atom have been recalculated anew, using the most accurate Miranda values of the free neutral TF function.
