实验数据之间的比较，INCL和其他核模型中可用的Geant 4工具包。用于比较的数据来自GANIL设施实现的碎裂实验。该实验的主要目的是测量95.A MeV 12 C束与厚PMMA（塑料）靶碰撞产生的发射粒子的产生率和角分布。本文将介绍最新版本的核内级联列日程序，该程序扩展到了用于离子束治疗的核-核碰撞。该代码以及JQMD和Geant 4二进制级联已与这些强子疗法为导向的实验数据进行了比较。从比较的结果表现出的模型和实验数据之间的总体定性协议。然而，在定量层面上，已经表明这三种模型都不能精确地再现所有数据。核-核扩展的INCL，这是不是足够的预测离子束治疗的应用，但已被证明是有竞争力的其他核碰撞代码。
Comparisons between experimental data, INCL and other nuclear models available in the Geant4 toolkit are presented. The data used for the comparisons come from a fragmentation experiment realised at GANIL facility. The main purpose of this experiment was to measure production rates and angular distributions of emitted particles from the collision of a 95.A MeV 12C beam and thick PMMA (plastic) targets. The latest version of the Intra Nuclear Cascade of Liege code extended to nucleus-nucleus collisions for ion beam therapy application will be described. This code as well as JQMD and the Geant4 binary cascade has been compared with these hadrontherapy-oriented experimental data. The results from the comparisons exhibit an overall qualitative agreement between the models and the experimental data. However, at a quantitative level, it has been shown that none of this three models manage to reproduce precisely all the data. The nucleus-nucleus extension of INCL, which is not predictive enough for ion beam therapy application yet, has nevertheless proven to be competitive with other nuclear collisions codes.
