In the framework of Glauber optical limit approximation where Coulomb effect is taken into account, the elastic scattering differential cross section for halo nuclei with 12 C at 800 MeV/N has been calculated. Its sensitivity to the halo densities and the root mean square of the core and halo is the main goal of the current study. The projectile nuclei are taken to be one-neutron and two-neutron halo. The calculations are carried out for Gaussian–Gaussian, Gaussian–Oscillator and Gaussian-2 s phenomenological densities for each considered projectile in the mass number range 6–29. Also included a comparison between the obtained results of phenomenological densities and the results within the microscopic densities LSSM of 6 He and 11 Li and microscopic densities GCM of 11 Be where the density of the target nucleus 12 C obtained from electron- 12 C scattering is used. The zero range approximation is considered in the calculations. We found that the sensitivity of elastic scattering differential cross section to the halo density is clear if the nucleus appears as two clear different clusters, core and halo.
