• The clustering mechanism is investigated starting from realistic nuclear forces. Under the independent-pair approximation the reaction matrix theory is applied to cluster states. In the case of neglecting inter-cluster motions, it is a kind of restricted Brueckner-Hartree-Fock calculation. An adequate method is presented for solving the reaction matrix equation in the cluster-orbital space. It is found that the clustering-induced attraction of the effective interaction works to enhance the clustering interdependently. As an attempt to treat the interdependence between the inter-cluster motion and the two-particle ladder correlation, we present a Brueckner-Generator-Coordinate method applied to the α-α scattering problem, where the Hill-Wheeler equation and the reaction matrix equation are solved self-consistently. The experimental α-α scattering phase shifts are well reproduced by taking account of the dynamical change of the effective interaction arising from complicated many-body effects.
