Abstract ：Within the isospin-dependent quantum molecular dynamics model, we investigate the nuclear collective flows produced in semi-central 197 Au+197 Au collisions at intermediate energies. The neutron–proton differential flows and difference of neutron–proton collective flows are sensitive to the momentum-dependent symmetry potential. This sensitivity is less affected by both the isoscalar part of nuclear equation of state and in-medium nucleon–nucleon cross sections. Moreover, this sensitivity becomes pronounced with increasing the rapidity cut.
