By employing a new threshold detector that utilizes the inelastic scattering reaction to the isomeric state of Ba-137, the time-integrated neutron flux above 1.9 mev was measured in the General Atomic Triga reactor. The values compare favorably with those extrapolated from measurements of the flux above 2. 9 mev given by the standard sulfur pellet method, and evidence thus far indicates that the new method may provide a whole new series of threshold detectors.
