Lattice vibrations are investigated by the model pseudopotential of Krasko and Gurskiy. Electrostatic interaction makes the lattice unstable as regards tetragonal shear. The band structure energy stabilizes the lattice. In a calculation of lattice vibrations ion repulsion can be neglected. The influence of exchange correlation effects on calculated parameters is examined.
