Abstract
The results for the phonon dispersion curves along the major symmetry directions, second order elastic constants (SOEC) and zero point energy are obtained on the basis of modified scheme, centered around an empirical Morse potential for some fcc metals. This exponential potential is less parametric, which incorporates the exchange and correlation effects due to electrons in a simple and effective manner. These above computed results are compared with experimental findings with remarkable success.
