Abstract
The nucleus-nucleus cross sections(σNN) include the protonproton cross section,neutron-neutron cross section, and neutron-proton cross section. σNNchange with the variations of the incident energies and the densities. Some parameterizations of σNN as a function of incident energy and density have been proposed in the theoretical and experimental study of nuclear reactions. Through the calculation of reaction cross sections of 12C+12C at different energies, the effect of different σNN parameterizations in the reaction cross sections of 12 are studied.
