Study of incident energy and isospin dependencies of total reaction cross section via the BUU model Original Research Article

The incident energy and isospin dependencies of total reaction cross sections σR have been researched by using the Boltzmann–Uehling–Uhlenbeck (BUU) model. When the width parameter of square-type or HO-type density distribution is obtained by fitting the σR at relativistic energies, the calculated result with BUU-model can reproduce the experimental data at intermediate energies better than that with Glauber-model of optical limit approximation. The systematical underestimation of σR at intermediate energy was removed out by BUU calculation framework. It is found that σR is sensitive to nuclear equation of state (EOS). It is also found that the difference factor (d) defined in text is sensitive to the nuclear structure such as neutron halo and neutron skin, etc.
