We calculate the spin susceptibility in the s_\ifmmode±\else\textpm\fi and s++ superconducting states of the iron pnictides using the effective five-orbital model and considering the quasiparticle damping. For the experimentally evaluated magnitude of the quasiparticle damping and the superconducting gap, the results at the wave vector \ensuremath≃(\ensuremathπ,0) show that the s_\ifmmode±\else\textpm\fi state is more consistent with the neutron scattering experiments, while for larger quasiparticle damping and the superconducting gap, the s++ state can be more consistent. To distinguish between two cases that reproduce the experiments at the wave vector \ensuremath≃(\ensuremathπ,0), we propose to investigate experimentally the wave vector \ensuremath≃(\ensuremathπ,\ensuremathπ).
