Cross‐section measurements were made of prompt γ‐ray production as a function of incident neutron energy on a 48Ti sample. Partial γ‐ray cross sections for transitions in 45–48Ti, 44–48Sc, 42–45Ca, 41–44K, and 41–42Ar have been determined. Energetic neutrons were delivered by the Los Alamos National Laboratory spallation neutron source located at the LANSCE/WNR facility. The prompt‐reaction γ rays were detected with the large‐scale Compton‐suppressed germanium array for neutron‐induced excitations (GEANIE). Neutron energies were determined by the time‐of‐flight technique. The γ‐ray excitation functions were converted to partial γ‐ray cross sections taking into account the dead‐time correction, target thickness, detector efficiency, and neutron flux (monitored with an in‐line fission chamber). The data will be presented for neutron energies between 1 to 250 MeV. These results are compared with model calculations that include compound nuclear and pre‐equilibrium emission.
