当入射粒子具有足够小的德布罗意波长以与单个核子相互作用时，核内级联模型通常被认为是有效的。在此基础上，核子诱导反应中的入射能量通常被引用为200 MeV的下限。在这里，这一说法受到质疑。使用了一种实用的方法，将Liège核内级联模型的预测与入射能量在40到250 MeV之间的现有数据进行了比较。结果发现，当能量远低于上述极限时，该模型给出了令人惊讶的好结果。结果还与该能量范围内常用的其他模型的预测结果进行了比较。
The intranuclear cascade model is generally considered to be valid when the incident particle has a sufficiently small de Broglie wavelength to interact with individual nucleons. On this basis, a lower limit of 200 MeV is usually quoted for the incident energy in nucleon-induced reactions. Here this statement is questioned. A pragmatic approach is used, which compares the predictions of the Liège intranuclear cascade model with available data at incident energy between 40 and 250 MeV. It is found that this model gives surprisingly good results at energies well below the limit mentioned above. Results are also compared with the predictions of other models commonly used in this energy range.
