| Research Abstract |
To study the applicability of a new generation scintillation detector LaBr_3 for measurements of neutron capture cross sections for fast neutrons, its fundamental performances, such as energy resolution and response functions, were measured. Calorimeters composed of LaBr_3 scintillation detectors were designed and their performances were evaluated using the Monte Carlo simulation code, where their fundamental data on energy resolutions and response functions were used. The simulation showed that the LaBr_3 based calorimeter works as a powerful tool for the measurements of neutron capture cross sections.
