摘要: The elastic scattering of the halo nucleus 6He from heavy targets such as 197Au and 208Pb has been investigated in order to explain Coulomb rainbow peak due Fresnel-type diffraction observed experimental data. In examine role nuclear potential describe + systems, we have used no-core shell model, few-body Gaussian-shaped density distributions at various energies. microscopic real parts complex obtained by using double-folding model for each distribution phenomenological imaginary potentials taken standard Woods-Saxon shape. We that fewbody given results, a classical pattern with whereas shell-model provided reduction Fresnel more consistent results
