Description

A three-body cluster model involving microscopic nonlocal interactions is developed and compared with a fully microscopic cluster model. The energy-independent nonlocal interactions are obtained from a renormalization of the energy-dependent kernels of the resonating-group method. Such interactions are derived for the αα and αn systems. The role and importance of nonlocality are discussed. These interactions are employed in three-body studies of the αnn,ααn, and 3α descriptions of the 6He, 9Be, and 12C nuclei. A comparison with fully microscopic calculations provides a measure of the importance of three-cluster exchanges in those states. The differences between both cluster-model calculations are in general small, except in the densities at short distances
