  In order to clear up the sensitivity of the nucleus-nucleus scattering to the
nuclear matter distributions of exotic halo nuclei, we have calculated
differential cross sections for elastic scattering of the $^6$He and $^{11}$Li
nuclei on several nuclear targets at the energy of 0.8 GeV/nucleon with
different assumed nuclear density distributions in $^6$He and $^{11}$Li.
