Based on the available experimental data for total cross section, nonelastic cross section, and elastic scattering angular distribution of n + 32,natS, a set of neutron optical potential parameters is obtained. The complete sets of nuclear data for n + 32,34S < 20 MeV are calculated. These sets include cross sections, angular distributions of elastic scattering, energy spectra and/or double-differential cross sections of all emitted particles, and gamma production data (production cross sections and multiplicity, energy spectra) in all kinds of reactions. The calculated results are generally in good accordance with experimental data and are compared with JENDL-3.3.
