The elements studied are: 4 rare gases, Ne, Ar, Kr and Xe, which at solid state have fcc crystal structure , 7 metals with fcc, 3 metals with bcc and 3 rare earth metals with fcc structure (Ce, Yb, Th). Both the 12-6 Lennard-Jones and Mie potentials have been used. The data used in the formula expressed by Eq. ( ), taken from references , is presented in Table . 3.1 Values of binding energy using the 12-6 Lennard-Jones potential For this formulation Eq. ( ) has been used with the values n = 6 and m = 12. The results for 4 rare gases are presented in Table and compared to the ones obtained by Horton solving a two-equation system set by fit of two crystal properties: the sublimation energy and the 0 • K lattice size. The results for 8 metals are presented in Table and compared to the ones obtained by Heinz et al. and Kanhaiya et al. , who used a molecular dynamics approach. The results for molybdenum and tungsten are also provided but no comparison is available. Table presents the results obtained for 3 fcc rare earth metals, which are compared to the ones obtained by Kanhaiya et al. .
