Essay

In the dissertation, we used an ab initio version of the description of the interatomic interaction, based on the quantum-mechanical model of deformable and polarizable atoms. The role of the many-body interaction and the quadrupole deformation of electron shells of the atoms in the formation of elastic properties of atomic cryocrystals over a wide range of pressures have been analyzed. The developed theory is applied to the calculation of the Birch and Fuchs elastic moduli, the deviation from the Cauchy relation, the Zener elastic anisotropy coefficient for the entire series Ne-Xe. We have obtained good agreement with the experiment, including the structural fcc - hcp transition in xenon at 75 GPa.
