Abstract
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.
