Sensitivity of reaction cross sections to halo nucleus density distributions

In order to clear up the sensitivity of the nucleus-nucleus reaction cross sections σR to the nuclear matter distributions in exotic halo nuclei, we have calculated the values of σR for scattering of 6He, 11Li, and 19C nuclei on several nuclear targets at the energy of 0.8 GeV/nucleon. The calculations were performed in the “rigid target” approximation to the Glauber theory, different shapes of the nuclear density distributions in 6He, 11Li, and 19C being assumed.
