Abstract
  • The analysis of the EXAFS signals from 70Ge and 76Ge has evidenced the low-temperature effect of isotopic mass difference on the amplitude of relative atomic vibrations. This effect is reflected in the difference of the Debye-Waller factors of the first three coordination shells, and on the difference of nearestneighbour average interatomic distances, evaluated with femtometer accuracy. The experimental results are in agreement with theoretical expectations. (literal)
