Physics of the HADRON code: recent status and comparison with experiment

A recent version of the high-energy transport code HADRON is described in part of the hadron event generator. The improved cascade-exciton model was extensively tested by the experimental data for double differential cross sections for the (N, xN')-reactions. Good agreement with experiment in wide ranges of nucleon energies and target nuclei confirms reliability of the new physical model. Ways for further improvements are discussed
