A nuclear collision theory, in which the many-body correlation induced by the strong short-ranged repulsion and medium-ranged attraction of the realistic NN interaction is explicitly included, is applied to the deuteron+deuteron elastic scattering at low energies. Two-body correlation functions calculated by the present theory are very different from those of Hackenbroich et al. They contain not only the short-ranged suppressive correlation, but also the medium-ranged enhancing correlation. The former changes the shape of the d-d potential from a wine-bottle one. The latter makes the d-d potential much more attractive. This effect is necessary for reproducing a bump around θ_<cm>=90° in the experimental elastic differential cross section. The phase shifts evaluated by the present theory are compared with those from the resonating-group method.
