Lattice oscillations frequencies are calculated. On this basis the modification of lattice parameters for particles smaller than 5$μ$ and an incremented modification of nanodimension sized particles are studied. Magnification of lines intensities are related to transmitting oscillations and orientation oscillations frequency decrease is found.2 pagesOpticsAtomic and Molecular Clusterstext
