Description

The results of a systematic calculation of the moments of the phonon spectra for 20 alkali halides are reported. The relevant phonon spectra needed are taken from the Green's function compilations by Haridasan et al. The calculated moments show good agreement with the available experimental data for sodium, potasium and caesium halides. The moments deduced from Debye-Waller factor data and from specific heat data are mutually consistent. A critical inter-comparison of these moments in these crystals is made. (author)
