For this formulation Eq. ( ) has been used with the values of n and m taken from Magomedov's work . The results for 4 rare gases, 10 metals and 3 fcc rare earth metals are presented in Tables 5, 6 and 7, respectively, and compared to the ones obtained by Magomedov , who used an approach based on the preservation of measured quantities such as sublimation energy and thermal expansion coefficient. The approximation of interaction of only nearest-neighbor atoms was adopted.
