Gamma-Ray Spectra from the Interaction of 14-MeV Neutrons with Copper, Zirconium, and Antimony

High energy gamma-ray spectra from the radiative capture of 14-MeV neutrons in copper, zirconium, and antimony have been measured with a coincidence-anticoincidence telescope pair spectrometer. These spectra are compared with predictions from calculations using the semidirect (collective) capture model. The parameter values used were derived from other types of experiments and from nuclear models. Agreement is found both in shape and in magnitude without further adjustment of parameters. Partial radiative capture cross sections, obtained by integrating the gamma-ray spectra for gamma energies in excess of 14 MeV, are compared with values from other measurements.
