STRUCTURE FACTORS IN GERMANIUM AT 0.342 AND 1.382 MEV

Crystal structure factors have been measured for eight reflections in Ge using gamma radiation at 0.342 and 1.382 MeV. The uncertainty of th e measured structure factors is approximately 0.05 e.u. Laue-case rock ing curves exhibiting Pendellosung oscillations were recorded using a double-crystal spectrometer located next to a high-flux reactor. The m easured rocking curves were computer fit to obtain structure factors. Because the effects of anomalous scattering approach zero at high ener gies (1.382 MeV), anomalous scattering corrections for lower-energy me asurements (8, 59, and 342 keV) have been derived by comparing the hig h-energy results to the lower-energy results. Best estimates of struct ure factors are derived for 12 Ge reflections.
