RESUMO

In this work the lattice dynamics of inert gas crystals is described by anharmonic approximaticn. Force matrices and their respective dynamic matrices for the first and second FCC lattice neighboor are obtained. Th third order force tensors for interaction of two and three bodies are determined, as his dynamics tensors. The renormalized frequency of the phonon is obtained by considering in the calculation the first anharmonic contribution. Theoretical results are compared with experimental results to 36Ar.
