摘要: Fast neutron inelastic scattering cross sections for levels between 700- and 1400-keV excitation energy in /sup 232/Th have been measured using the (n,n') time-of-flight (TOF) technique. Measurements of 125-deg differential were made neutrons with a typical spread 8 to 10 keV, generated by 7/Li(p,n)/sup 7/ Be reaction. The incident energies covere three regions: (a) 950 1550 keV 50-keV intervals TOF spectrometer optimized detect 200 600-keV scattered neutrons, (b) 1200 2000 100-keV 400- 800-keV (c) 1700 2100 steps 800- 1300-keV neutrons. Throughout experiment, an overall resolution <15 was maintained. Level deduced from are compared (n,n'..gamma..) measurements ENDF/B-V evaluation. Angular distributions states 900-keV region at 1.2, 1.5, 2.0 MeV.
