Calculation of nucleus–nucleus cross sections at intermediate energies using Glauber theory

Abstract

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.
