Phonon dispersion relations In NDJ

摘要

The phonon dispersion relations of NDtI in sodium chloride phase has been measured by using both ion polaiizable three-body force shell model. This model includes three body interactions (TBI) in the framework of both ion polarizable, rigid shell model (BSM1). The values of the phonon frequencies evaluated by the present approach agree well with the experimental values. We also report two phonon IS / Raman spectra.
