Özet:

 

The two-body pairwise E.G.E.P. (Extended Generalized Exponantial Potential) type Morse potential and volume dependent energy are assumed to represent the total energy of the Ba crystal. The parametrized potential is used to   calculate the second- and third-order elastic constants Cij and   Cijk, pressure derivatives of bulk moduli and Grüneisen parameter   g . The phonon frequencies are also computed and plotted. The   obtained results are compared with available experimental data and, in   general, the agreement is good.
