The Efficiency Of Coincidence Spectroscopy With Two Semi-Conductor Detectors At 0.5 - 8 MeV Energy Region

The efficiency function of detector is provided by manufacturer only when user request to manufacture. Even in this case, these functions still need to be tested by experiments. The efficiency of spectrometer is a function which depend energy, measurement geometry and sample geometry. Further more in the coincidence spectrometer, the efficiency depend both of detector efficiencies and distribute cascade energy. So, determined efficiency function of coincidence spectrometer is very complex. This report presents the results of determining the relative efficiency of coincidence spectrometer at Dalat Nuclear Research Institute. The experimental was determined by 35Cl(nth,γ)36Cl reaction and interpolated for 0.5 - 8 MeV energy region. (author)
