An integral expression of the classical deflection function by the use of Mellin transformation has been presented, which is convenient for the differentitation with respect to the impact parameter b to give the relation between the rainbow scattering angle θ R and the reduced kinetic energy K of the incident particle. A simple and useful approximate formula, -θ R⋅K=0.29 γ+1.75, valid for the value of K not less than five, has been derived for the three-parameter(12, 6, 4)potential.
