• Intermediate energy α-α scattering is studied by the resonating group method with the Coulomb exchange kernel, in order to resolve the discrepancy between the potential tail for the S, D and G waves and that for higher partial waves which was reported in a previous phenomenological analysis but hardly understandable from a microscopic point of view. It is shown that this discrepancy can be removed if we employ the new solution of the phase shift analysis. Validity of the orthogonality condition model in the inelastic region is shown if a suitable imaginary potential is added to the direct potential. The real phase shifts of the I-wave dominated by the direct potential tail restrict the coupling constants of isoscalar mesons with nucleon as g_σ^2/4π=3.5⇾6 and g_ω^2/4π=8⇾11.
