Abstract The effect of momentum-dependent interaction on the kinetic energy spectrum of the neutron-proton ratio < (n/p)gas>b(Ek) for 64Zn+64Zn is studied. It is found that < (n/p)gas>b(Ek) sensitively depends on the momentum-dependent interaction and weakly on the in-medium nucleon-nucleon cross section and symmetry potential. Therefore<(n/p)gas>b(Ek) is a possible probe for extracting information on the momentum-dependent interaction in heavy ion collisions.
