Boltzmann-Uehling-Uhlenbech calculation of total reaction cross-section and fragmentation cross-section

. σ_ R , σ_-n and σ_-2n have been calculated via the BUU model with soft EOS and 0.8 times of σ_ Cug . The density distribution without any adjustable parameters which comes from the RMF model has been introduced into the BUU calculation to replace the normally used one-parameter square-type distribution. The calculated results can reproduce the experimental data well for both halo- and stable-nuclei-induced reactions. Here σ_-n or σ_-2n is calculated as the difference between σ_ R of halo nucleus and core nucleus, by assuming σ_ corr≃ 0 . It indicates that this assumption works very well at high energy in the BUU calculation. More experimental measurements are necessary to test the validity of this assumption at intermediate energy.
