Table 2 Lattice constants (a and c), cohesion energies (Ec), elastic constants (Cij) and bulk moduli (B0) of Al, Ni and Y fitted by the constructed potential and observed from experiments (Ref. 30, 31).Lattice constants a and c are expressed in Å, cohesion energies Ec in eV/atom, elastic constants Cij and bulk moduli B0 in Mbar.
