Abstract. The Liège intranuclear cascade model has been improved by allowing for multipion production in nucleon-nucleon collisions, a feature that is more and more relevant in nucleon-induced spallation reactions when the incident kinetic energy exceeds 2 GeV or so. A phase space model is presented for multipion production and tested by comparing with experimental data.
