In the dynamical theory of the anomalous transmission of x-rays through perfect thick crystals, the ratio of transmitted intensity to incident intensity depends upon [1 − Kf″Ge(θhkl)/f″Ge(0°)] exponentially. Here K is the polarization factor and the f″Ge(θhkl) and f″Ge(0°) are the imaginary parts of the atomic scattering factors of germanium at the angle θhkl and 0°, respectively. This paper describes the measurement of the ratio f″Ge(θhkl)/f″Ge for several different sets of planes in nearly perfect germanium crystals.
