Abstract
In order to study the interatomic correlation moments (QCM) and the me an square relative atomic displacements (MSRD), there has been employe d the correlative method of unsymmetrized self-consistent field (CUSF) . In tile second order of CUSP we have calculated the longitudinal and transversal components of QCM and MSRD between the nearest, second an d fourth neighbors, in the simple cubic lattice. The results are discu ssed in relation to those obtained previously for low-dimensional mode ls.
