Sensitivity of reaction cross sections to halo nucleus density distributions

Abstract

In order to clear up the sensitivity of the nucleus--nucleus reaction cross sections ${\sigma }_R$ to the nuclear matter distributions in exotic halo nuclei, we have calculated the values of ${\sigma }_R$ for scattering of ${}^6$He, ${}^{11}$Li, and ${}^{19}$C 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 ${}^6$He, ${}^{11}$Li, and ${}^{19}$C being assumed.
