According to the experimental data of total, nonelastic scattering cross sections and elastic scattering angular distributions of tungsten and its isotopes, a set of neutron optical model potential parameters is obtained. All of the reaction cross sections, angular distributions, energy spectra,  -ray production cross sections, -ray production energy spectra, and the double-differential cross section for neutron, proton, deuteron, triton, helium, and alpha emission are calculated and analyzed for n + 180,182,183,184,186,natW at incident neutron energies from 0.1 to 250 MeV based on the nuclear model theory, which combines the optical model, the unified Hauser-Feshbach theory and exciton model, and the coupled channel theory. Theoretical calculations are compared with existing experimental data and other evaluated data from ENDF/B6.8 and JENDL-3.3.
