|Title:||Phonon Spectra Of Randomly Disordered System|
|Abstract:||We study the phonon density of states of a three dimensional disordered mixed crystal NaClxBr1-x. The phonon structure is obtained by using a cluster method based on a continued fraction expansion of the Green function. The proposed dynamic model includes only short range interactions (first and second neighbors) but supports some qualitative features of the constituents binary alloys. © 1991.|
