Résumé : d+d (S-wave) elastic scattering phase shifts are studied in an extended microscopic cluster model in order to investigate cluster-breaking effects appearing in the low-energy scattering. The description of the cluster wave function is extended from a simple (0s) harmonic-oscillator shell model to a few-body model, in which the wave function of the sub-system is determined with the Stochastic Variational Method (SVM). To compare the cluster breaking effects with realistic and effective interactions, we employed the G3RS potential as a realistic interaction and the Minnesota (MN) potential as an effective interaction. The calculated phase shifts show that t+p and 3He+n channels are strongly coupled to the d+d channel for the case of the realistic interaction (G3RS). On the contrary, the coupling of these channels plays a relatively minor role for the case of the effective interaction (MN). © 2011 World Scientific Publishing Company.
