Nucleus–nucleus cross sections are calculated using nucleon–nucleus optical potentials in the framework of Glauber theory. The resulting cross sections are compared with experimental data. The reaction cross sections for various light nuclei including loosely bound nuclei are calculated from the nucleus–nucleus phase shift functions which need the nuclear density and the optical potential as an input. The calculated reaction cross sections in the energy range of 30 to 800 MeV/nucleon are in agreement with experimental data within error bars. The elastic differential cross sections of 4,6He+12C and 12C+12C are calculated at 41 MeV/nucleon and 30, 200 MeV/nucleon, respectively. At lower energy, a correction beyond the eikonal approximation improves the agreement between measured and calculated angular distributions significantly.

A method for calculating the complete expansion of the Glauber amplitude is applied to the elastic scattering of protons on a 6He target using correlated wave functions. The angular distribution measured at Tp = 700 MeV is very well reproduced by a no parameter calculation using a fully microscopic, 6-nucleon α + n + n-cluster wave function. The accuracy of various approximations for the Glauber amplitude is compared with the complete expansion calculation. The matter radius of 6He consistent with the analysis is 2.51 fm. Simple shell-model or di-neutron cluster-model wave functions fail in reproducing the angular distribution.

The energy dependence of the real part of the ion-ion interaction potential is studied using an energy density functional derived from the Negele realistic nucleon-nucleon interaction. It is found that the Negele force produces an ion-ion potential which varies slowly with energy compared to that derived using a simple two-body effective interaction.

A relativistic version of the two colliding nuclear matter approach together with the eikonal approximation are used to calculate the reaction cross-section σr for the spherically deformed pair C12-N17. Both the energy and the orientation dependence of the σr are studied. A maximum variation of 13% was found in σr due to all possible orientations of the deformed nucleus.
