We propose a way to determine the pairing state of the iron pnictide superconductors exploiting the momentum (Q) scan of the neutron scattering data. We investigate the spin susceptibility in theandsuperconducting states for various doping levels using the effective five-orbital model and considering the quasiparticle damping. The peak position of the intensity shifts from the position on the lineto that on the lineas the doping level is decreased from electron doping to hole doping. We find that the Q dependence of the ratio of the intensity in the superconducting state to that in the normal state is qualitatively different between the-wave and-wave pairings. We propose to investigate experimentally this ratio in Q space to distinguish the two pairing states.
