Brueckner-Generator-Coordinate Method and Application to - Scattering

Abstract

In a process accompanied by a large structure change such as clustering phenomena, there appears the interdependence between a dynamical motion of the whole system and the nucleon-nucleon effective interaction. As an attempt to treat such an effect, we present a Brueckner-Generator-Coordinate Method applied to the α-α system, where the two-particle-ladder correlation and the inter-cluster motion are solved self-consistently starting from realistic nuclear forces. The physical content is discussed in comparison with the adiabatic treatment in our previous work. The experimental α-α scattering phase shifts are well reproduced by taking account of the dynamical change of the effective interaction which is real in the α-α system.
