AbstractThe rotational collective flow in reactions of (58)Fne+ Fe-58 and Ni-58 + Ni-58 + 40 MeV/u for different impact parameters was studied within the framework of IQMD model, by analyzing the mid-rapidity azimuthal distribution and calculating semi-quantitatively the rotational observables. A strong isospin dependence of rotational collective flow has been found, namely, the more neutron-rich system exhibits stronger rotational collective flow. This isospin dependence is more appreciable in semi-peripheral collisions, and it mainly results from the isospin dependence of N-N cross section and the symmetry energy. Meanwhile, it is indicated that the rotational collective flow depends strongly on the impact parameter, namely, it increases with increment of impact parameter from near central to peripheral collisions and then decreases, finally disappears in the most peripheral collisions.
