Query: Interatomic Correlations Moments of Atoms in the Two-Dimensional
  Hexagonal Lattice by Using Morse and Lenard-Jones Potentials   In this work we investigate the interatomic correlation moments in
two-dimensional model of a weakly anharmonic crystal (i.e., not very high
temperatures) with hexagonal lattice, using the Correlative Method of
Unsymmetrized Self-Consistent Field (CUSF). The numerical results are obtained
(and compared) by using the Morse and Lenard-Jones potentials.
