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 σ R to the nuclear matter distributions in exotic halo nuclei, we have calculated the values of σ 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.

Differential elastic nucleus-nucleus scattering in complete Glauber theory

“…An example of such calculations for the differential elastic and reaction cross sections for 11 Li - 12 C scattering can be found in Refs. 4,5 In this paper the analytical calculations of the differential elastic cross sections for 12 C -12 C and 11 Li - 12 C scattering have been carried out in the complete Glauber theory in the generating function approach Ref. 6 The results have been obtained for several commonly used forms of the nuclear density, which allows one to get an insight to the possible nuclear correlations, in particular, to those related to the shell structure of the halo nucleus 11 Li.…”
