Measured cross sections per atom of natural titanium for neutron elastic scattering and for inelastic scattering to levels in /sup 48/Ti for incident neutron energies between 4.07 and 8.56 MeV are given and compared with previous results. ENDF/B III MAT 1144 angular distributions are in reasonably good agreement with experimental results at angles less than 40 degrees but differ by as much as an order of magnitude at larger angles. The ENDF/B III MAT 1144 angle- integrated elastic scattering cross sections agree within experimental uncertainties with experimental results at energies below 6.44 MeV but rise 20% above measured values at 8.56 MeV. ENDF/B III MAT 1144 inelastic scattering cross sections to discrete levels in /sup 48/Ti are in poor agreement with experimental data because of the predominance of continuum inelastic scattering in ENDF/B III MAT 1144. An evaporation model of inelastic scattering to the continuum is found to be valid for inelastic scattering to levels of excitation energy greater than 6 MeV but is questionable for inelastic scattering to levels of lower excitation energy.
