Abstract

The235U fission neutron spectrum averaged cross section for the50Ti(n,α)47Ca reaction was experimentally determined by irradiation of titanium with reactor neutrons. A value of (9.7±1.1) μb was found for this cross section, using (307±11) μb for the48Ti(n,p)48Sc spectrum-averaged cross section that was used as a standard. The50Ti(n,α)47Ca spectrum-averaged cross section was also semiempirically evaluated by numerically integrating, through the ENDF/B-V representation of the235U fission neutron spectrum, the available experimental differential cross section data.
