The neutron radiate capture cross sections of natural Zr are calculated in the neutron incident energy region from 0.01 MeV to 20 MeV. In the calculations, photon transmission coefficients of the compound statistical processes are calculated by solving the cascade gamma deexcitation processes of the compound nucleus. The nonstatistical effects of the neutron radiate captures, the radiate captures in the shape elastic scattering channels and the compound elastic scattering channels as well as the direct-semidirect captures are considered carefully in the calculated energy region. The calculated results are in better agreement with the experimental values.
