Abstract
This article intends to examine quantitatively the dynamic aspect of the phenomenological moving-source model in nucleus-nucleus collisions in the Fermi domain. The reactions, 36Ar+108Ag (35 MeV u-1)and14N+108Ag (35 MeV u-1), have been studied in terms of the BUU dynamic program. It has been found that the intermediate rapidity source (IRS) components of emitted neutron data extracted from the moving-source fitting approach do come from the very early stage of collisions, and are identified with pre-equilibrium emissions. One may define two time intervals as the pre-equilibrium emission time scale: the first chance collision time tau fcc and the classical transit time tau T=2(RT+RP)/v0, where v0 is the beam velocity, and RT and RP are the radii of the target and projectile nucleus, respectively. The two time scales are indicated to be of nearly the same values for the two reactions concerned. The IRS components quantitatively correspond to the major part of emitted neutrons within this time interval in the BUU frame.
