摘要：

Information on the temperature dependence of the atomic correlation functions in quasicrystals has been obtained from Mossbauer and high resolution neutron spectroscopies. A pronounced nonlinear decrease is observed at high temperature for the purely elastic contribution. This indicates localized vibrational states within a length scale of about 10 angstrom.
