AMPLITUDES OF VIBRATION AND X-RAY SCATTERING OF CRYSTALLINE LITHIUM HYDRIDE AND LITHIUM DEUTERIDE: 300 K TO 20 K
Abstract
Intensities of Laue-Bragg scattering from powdered crystals of LiH and LiD were obtained at 20, 77 and 194, and 303 K with a recording G-M counter spectrometer and a special Dewar specimen mount. Relative crystal-structure factors and relative atomic form factors were calculated from the intensities; absolute atomic form factors and characteristic temperatures were obtained from the relative form-factor values. Temperature coefficients and amplitudes of vibration were calculated from the characteristic temperatures. Electron- density distributions for KiH, obtained from the absolute atomic-form-factor data, were used to calculate radial charge distributions. Evidence was discovered which suggested a change in the ionization state of the crystals with changes in temperature.
