On the interatomic correlations and mean square relative atomic displacements in an anharmonic simple cubic lattice

In order to study the interatomic correlation moments (QCM) and the mean square relative atomic displacements (MSRD), there has been employed the correlative method of unsymmetrized self-consistent field (CUSF). In the second order of CUSF we have calculated the longitudinal and transversal components of QCM and MSRD between the nearest, second and fourth neighbors, in the simple cubic lattice. The results are discussed in relation to those obtained previously for low-dimensional models. © World Scientific Publishing Company.
