The modified intranuclear cascade evaporation model combining the Monte Carlo method for the simulation of non-equilibrium particle emission and deterministic algorithm for the description of equilibrium de-excitation is discussed. The nuclear level density for equilibrium states is calculated using the generalized superfluid model taking into account shell and collective effects. The inverse reaction cross-sections are calculated by the nuclear optical model. The model was used for the analysis of radionuclide yields in proton-induced reactions at energies 0.8–2.6
GeV. The results of calculations show the advantage of the model proposed in accuracy of predictions compared with other popular intranuclear cascade evaporation models.
