| 英文摘要 | We have measured the fragmentation cross sections of Fe-56 on Al, C and CH2 targets at 471 A MeV using CR-39 plastic nuclear track detector. Cross sections for H target are calculated based on the results of C and CH2 targets. Here, we present the results of total charge changing cross sections and the partial cross sections for fragments with charge Z(F) >= 5. The total charge changing cross sections agree well with other previous experimental results at different energies and the theoretical prediction of Bradt-Peters semi-empirical formula, which are approximately independent of the beam energy but increase with the increase of the target mass. The partial cross sections show a significant enhancement for the fragments with even-Z nuclei, especially for the fragments with charge 10 <= Z(F) <= 20. For the collisions of Fe-56 on all targets reported in this paper, we firstly present the partial cross section results of the fragments with charge 5 <= Z(F) <= 9 using CR-39 detector. Finally, the partial cross sections is compared with the prediction of the improved quantum molecular dynamical model (ImQMD) and the GEMINI model, the production of charged projectile fragments can be well described by the models. |
