Abstract：
The dynamics of linear momentum dissipation in the reaction of 50MeV/u ¹²C with ²⁰⁹Bi has been studied within the BUU approach. For the peripheral collision,deep inelastic reaction process similar to what observed at lower energy region seems to persist, indicating an important effect of the mean field. For the central collision, complete momentum transfer is inhibited from the preequilibrium particle emission. The predictions of BUU equation reasonablily agree with the experimental data.
