Abstract：
By fitting the experimental data of total, nonelastic and elastic scattering angular distributions for n+Zr reactions, a set of neutron optical model potential parameters is obtained. The inelastic scattering angular distributions of discrete levels and double differential cross sections are calculated and analyzed by using the distorted wave Born approximation theory based on the unified Hauser Feshbach and the exciton model. With the fitting procedure the neutron induced level deformation parameters are obtained. The results indicate that the calculated results of the inelastic scattering angular distributions and total outing neutron double differential cross sections for n+ ^90,91,92,94Zr can be obtained, which are all in good agreement with the experimental data.
