THEORETICAL CALCULATION ON THE PAIR POTENTIALS BETWEEN LIGHT RARE-EARTH METALLIC ATOMS

In order to calculate the pair potentials between light rare-earth metallic atoms with double hexagonal close-packed (dhcp) crystal structure, a M\ddot\rm obius inversion transform formula for the dhcp structure is proposed. The pair potentials for the light rare-earth atoms are calculated by this formula. These pair potentials are fitted to the analytic Morse-type potential expressions.
