Nuclear data were evaluated on 90,91,92,94,96Zr, 93Nb and 182,183,184,186W for neutron and proton incidence up to 200 MeV. Optical model potential parameters were searched to give good agreements with experimental values of elastic-scattering, total, and total-reaction cross sections. The GNASH pre-equilibrium/statistical model code was used for evaluations of particle-production cross sections. Since the direct inelastic-scatterings induced by the excitations of giant resonances are not negligible for these nuclei, the calculation was performed to take them into consideration. For composite-particle emission cross sections from pre-equilibrium states, semi-empirical methods were utilized to give good agreements with experimental results. We also calculated isotope-production cross sections. Evaluated cross sections were compared with values by measurements and the LA150 evaluations.
