Abstract
Using an accurate numerical solution of the Thomas—Fermi model with quantum-mechanical corrections, the author obtains a description of coherent and incoherent scattering of x rays by the inert gases, which is in excellent agreement with detailed Hartree—Fock calculations. The results are somewhat better than those given by the Thomas—Fermi—Dirac model, and are a substantial improvement over those given by the Thomas—Fermi model alone.Keywords
