Abstract : The reaction cross-sections are calculated for various Li, Be and B+12C systems, also involving the exotic halo nuclei, by using both the spherical and deformed relativistic mean field (RMF) densities in the finite range Glauber model with Coulomb effects included. For reactions at higher energies (>500 MeV/nucleon), both the spherical and deformed RMF densities give similar results for all the isotopic chains of exotic nuclei studied here. On the other hand, for reactions between stable nuclei, though the two RMF densities (spherical and deformed) result in simply an overall normalization for the excitation functions, it gives an improved comparison with experimental data, at high and low energies for spherical and deformed densities, respectively. A similar normalization is obtained for other densities, which means to stress that, though densities are different, they do not change much with the excitation energy. Finally, some details of the characteristic properies of exotic light nuclei are shown to contain the deformation effects of the halo nuclei.
