Abstract

The ultrarelativistic quantum molecular dynamic (UrQMD) model is widely applied for simulation of multi-particle production in hadron-nucleus and nucleus-nucleus interactions at high energies. In order to describe evaporation and multi-fragmentation of nuclear residuals we have enlarged the UrQMD model version 3.4 with the statistical multi-fragmentation model (SMM). The coupling of UrQMD and SMM allows one to well describe neutron and nuclear fragment productions using the EoS mode of the UrQMD model. The UrQMD 3.4 model enlarged by the SMM model can be applied at NICA and FAIR experiments.
