Intranuclear cascade plus evaporation models are able to describe spallation reactions using very few input, among which a mean field for nucleons and for pions, generally under the form of crude potential wells. The influence of this ingredient, especially of the isospin and the energy-dependence of the nucleon mean field is investigated. The influence of the presence of a pion mean field is also studied.
