Abstract.
\(\sigma_{\rm R}\), \(\sigma_{-n}\) and \(\sigma_{-2n}\) have been calculated via the BUU model with soft EOS and 0.8 times of \(\sigma_{\rm Cug}\). 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 \(\sigma_{-n}\) or \(\sigma_{-2n}\) is calculated as the difference between \(\sigma_{\rm R}\) of halo nucleus and core nucleus, by assuming \(\sigma_{\rm corr}\simeq 0\). 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.
