Abstract
A quantum reaction approach to low-energy collisions of weakly bound few-body nuclei, based on the time-dependent wave-packet method, is presented in detail. In contrast to existing models that use this perspective, the approach separates the complete and incomplete fusion from the total fusion. Calculations performed within a one-dimensional model with two degrees of freedom for Li-6 + Bi-209 at energies around the Coulomb barrier demonstrate that converged reliable excitation functions for total, incomplete, and complete fusion can be obtained with this type of approach.
