500个MeV/nucleon碳离子在不同靶材料上的全部和部分碎裂截面
Total and Partial Fragmentation Cross-Section of 500 MeV/nucleon Carbon Ions on Different Target Materials
摘要：
通过使用基于薄和厚双面微带硅探测器的实验装置，已经可以识别由于非常高能量的初级离子在不同目标上的相互作用而产生的碎裂产物。在这里，我们报告的总截面和部分截面测量GSI（Gesellschaft Fur Schwerionenforschung），达姆施塔特，为500 MeV/n能量$^{12}C$束入射到水（烧瓶中），聚乙烯，有机玻璃，碳化硅，石墨，铝，铜，铁，锡，钽和铅的目标。计算结果与GEANT 4（v4.9.4）和FLUKA（v11.2）蒙特卡罗模拟程序的预测结果进行了比较。
英文摘要：
By using an experimental setup based on thin and thick double-sided microstrip silicon detectors, it has been possible to identify the fragmentation products due to the interaction of very high energy primary ions on different targets. Here we report total and partial cross-sections measured at GSI (Gesellschaft fur Schwerionenforschung), Darmstadt, for 500 MeV/n energy $^{12}C$ beam incident on water (in flasks), polyethylene, lucite, silicon carbide, graphite, aluminium, copper, iron, tin, tantalum and lead targets. The results are compared to the predictions of GEANT4 (v4.9.4) and FLUKA (v11.2) Monte Carlo simulation programs.
