EmpiricalT3/2law for atomic thermal vibration parameters

摘要

The Debyehyphen;Waller factor, as measured by xhyphen;ray and neutron diffraction and Mouml;ssbauer techniques, is shown to be of the forma+bT3/2over an extensive temperature range in a diverse set of crystalline solids. This twohyphen;parameter empirical relationship may be interpreted within the framework of the Debye theory, modified to include quasiharmonic effects.
