Abstract
Results of computer calculations of normal modes of certain one-, two-, and three-dimensional harmonic lattices are displayed, discussed, and correlated with the frequency spectra for similar lattices reported in an earlier paper. An interesting feature of the results is that localization of the displacements in the normal modes is associated with certain ranges of concentration and mass ratio.Keywords
