We investigate the role of momentum-dependent interactions on the fragmentation of asymmetric colliding nuclei using isospin-dependent quantum molecular dynamics model. In particular, we study both central and peripheral collisions of 40Ar+64Cu, 40Ar+108Ag and 40Ar+197Au. Our investigations reveal significant role of momentum-dependent interactions on the fragmentation pattern in asymmetric colliding nuclei. The relative role of different model ingredients changes depending on the asymmetry of the colliding pair.

Abstract


We investigate the role of momentum-dependent interactions on the fragmentation of asymmetric colliding nuclei using isospin-dependent quantum molecular dynamics model. In particular, we study both central and peripheral collisions of 40Ar+64Cu, 40Ar+108Ag and 40Ar+197Au. Our investigations reveal significant role of momentum-dependent interactions on the fragmentation pattern in asymmetric colliding nuclei. The relative role of different model ingredients changes depending on the asymmetry of the colliding pair.
