The ratio of ground-state transitions to excited-state transitions following neutron absorption in 10B has been measured for the 20- to 1000-keV neutron energy region. Face-to-face silicon surface-barrier detectors were used to detect reactions and measure the total energy of the emitted alpha and lithium particles. The Oak Ridge Electron Linear Accelerator was used as a white neutron source, and time of flight was used to determine the neutron energy. The ratio varied from 0.064 at the lowest energies to 0.72 at 920 keV. The current measurements tend to be smaller than the currently accepted values by 10 to 30% in the 100- to 600-keV energy region.
