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

Abstract
Crystal structure factors have been measured for eight reflections in Ge using gamma radiation at 0.342 and 1.382 MeV. The uncertainty of the measured structure factors is approximately 0.05 e.u. Laue-case rocking curves exhibiting Pendellosung oscillations were recorded using a double-crystal spectrometer located next to a high-flux reactor. The measured rocking curves were computer fit to obtain structure factors. Because the effects of anomalous scattering approach zero at high energies (1.382 MeV), anomalous scattering corrections for lower-energy measurements (8, 59, and 342 keV) have been derived by comparing the high-energy results to the lower-energy results. Best estimates of structure factors are derived for 12 Ge reflections.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
