Measurements have been made of gamma-ray production due to neutron interactions with samples of boron for incident neutron energies between 0.1 and 25 MeV. For {sup 11}B a 54-g sample of naturally-occurring boron in the shape of a solid cylinder was used. For {sup 10}B, samples enriched to 95% in the {sup 10}B isotope were used. One sample, about 49 g, was used to obtain {gamma}-ray data following inelastic scattering; the other sample, of about 15 g, was used to delineate the production of the 478-keV gamma ray following the {sup 10}B(n,a){sup 7}Li reaction for E{sub n} between 0.1 and 4 MeV. The Oak Ridge Electron Linear Accelerator (ORELA), a white source, was used to provide the incident neutrons. Data were obtained using a high-purity intrinsic-germanium photon detector positioned at 125 deg with respect to the indirect neutron beam. Because the peak shapes in the raw data were substantially broadened by Doppler motion, peak yields were determined with graphite-interactive methods. Except for the 478-keV gamma ray for E{sub n} < 1 MeV, the {gamma}-ray production cross sections are all small, the largest being <200 mb.
