Momentum dependent interactions and the asymmetry of the reaction: Multifragmentation as an example - art. no. 054603

We discuss the importance of momentum dependent interactions in explaining the multifragmentation in asymmetric reactions by comparing the results wit h O-16-induced emulsion data. The reactions are simulated within a quantum molecular dynamics model and the clusterization is performed with the minim um spanning tree method. Our results clearly indicate that the inclusion of momentum dependent forces improves the agreement with the measured atomic number distribution. The simple static interaction fails to explain the exp erimental data. We also discuss the universal dependence of the effect of m omentum dependent interactions on the asymmetry of a reaction.
