✦ Synopsis

A systematic study of elastic proton and neutron scattering as well as (p, n) charge exchange reactions was undertaken in the context of the JLM microscopic framework in order to test the isovector part of the potential. The study included the stable nuclei 48 Ca, 90 Zr, 120 Sn and 208 Pb in the energy range of ∼ 25-45 MeV and the halo nucleus 6 He at ∼ 40 MeV. It was found that the stable nuclei data can be reproduced, by an adjustment of the isovector part through a renormalization factor, λ isov ∼ 2-2.5. The required isovector adjustment for the halo nucleus data will be discussed.
