Abstract
The purpose of this novel work is to calculate the cohesive energy of FCC transition metallic nanoparticles that comprise up-to-12215 atoms. In this paper, a modification of the universal pair potential function proposed by Rose et al. (1981), is introduced. While Rose's function works
fine for bulk materials, it fails to predict the experimental results for FCC metallic nanoparticles. The Chen-Mobius method was used to construct the modified pair potential which had been summed over all pairs of atoms within a given nanoparticle. Although simple, this method accurately
predicts the experimental cohesive energy reported for FCC-transition metallic nanoparticles in the literature.
