Isospin dependence of the microscopic JLM model Original Research Article

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 48Ca, 90Zr, 120Sn and 208Pb in the energy range of ∼25–45 MeV and the halo nucleus 6He 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, λisov∼2–2.5. The required isovector adjustment for the halo nucleus data will be discussed.
