We propose a new model to describe the alpha + alpha interaction that takes into account the Pauli nonlocality through a velocity-dependent term. With this interaction, we describe very well the phase shifts obtained from elastic scattering data analyses for alpha + alpha at low energies. We also obtain a good description of the s-wave resonance related to the Be-8 ground-state. The model is based on double-folding procedures and, therefore, it can easily be extended to other systems. We present a test of the model in the case of elastic scattering for He-4 + Pb-208. (AU)
