| 中文摘要 | it is shown that the locus of the f' + if '' plot in the complex plane, f' being determined from measured f '' by using the dispersion relation, looks like a semicircle very near the absorption edge of ge. the semicircular locus is derived from a quantum theory of x-ray resonant scattering when there is a sharp isolated peak in f '' just above the k-absorption edge. using the semicircular behavior, an approach is proposed to determine the anomalous scattering factors in a crystal by fitting known calculated values based on an isolated-atom model to a semicircular focus. the determined anomalous scattering factors f' show excellent agreement with the measured values just below the absorption edge. in addition, the phase determination of a crystal structure factor has been considered by using the semicircular behavior. |
