    "abstract": "We study elastic N$\\alpha $ scattering and produce a quantitative correlation\nbetween the range of the effective potential and the energy of the system. This\nallows the identification of the waves and energies for which the scattering\nmay be said to be peripheral. We then show that the corresponding phase shifts\nare sensitive to the tail of the NN potential, which is due to the exchange of\ntwo pions. However, the present uncertainties in the experimental phase shifts\nprevent the use of N$\\alpha $ scattering to discriminate the existing models\nfor the NN interaction.",
