Abstract：
Preequilibrium neutron emissions from nucleus-nucleus collisions ³⁶Ar+ ¹⁰⁸Ag (35MeV/u) and ¹⁴N+ ¹⁰⁸Ag (35MeV/u) are simulated in the BUU model. Thesimulations are in agreement with the intermediate rapidity source (IRS) parts in the moving source fit approach, which indicates that the IRS parts come from the very early stage of collisions, and are equivalent to preequilibrium emissions. The time interval of the preequilibrium neutron emission process is studied in terms ofnucleon-nucleon collisions.
