INVESTIGATION OF HEAT VIBRATIONS IN SOLIDS BY USING X-RAYS
Abstract
Measurements were reported of X-ray integrated intensities at low and high temperature, carried out on several diffraction lines of Ag, Au, Pt, and Pb powders in vacuum, to determine the temperature dependence of characteristic temperature. For Au and Pt a decrease of characteristic temperature with temperature, resulting from volume expansion, was found. In the case of Ag, the decrease of characteristic temperature with temperature exceeds that due to volume expansion. For Pb, the disagreement in characteristic temperature values obtained from the various diffraction lines did not allow any conclusion. (Author)
