Research Abstract

The project focused on the following items.
1)Characteristic Feature of the Instrument Function : The instrument function is the transfer function of input and output signal functions.
2)Re-Evaluation of Gamma-Ray (Photon) Energy : The centroid of a normal distribution folded in the instrument function is the intrinsic position corresponding to the reference energy. Discovery of this finding is the most striking result of the project.
3)Development of the System Calibration Method : The system calibration, i.e., nonproportionality correction has established.
4)Quantitative Understanding of Summing Phenomena : The random summing component can be generated by photon-material interaction events without the detector by Bremsstrahlung photons, and within the detector by the Compton scattered electrons. Empirical functional model of the random summing has been proposed.
5)Event Analysis of Photopeak Profile Creation in Gamma-Ray Spectra : Effect of base profile for precise measurement of photon energy in prompt gamma-ray analysis has benn examined. A formula has been proposed for the quantitative characterization of the base profile.
It is worth noting that the International Committee for Radionuclide Metrology (ICRM) Working Group on 'Beta-particle and gamma-ray spectrometry' has proposed a new international cooperation action project, "LINE SHAPE RESPONSE FUNCTIONS WITH PHYSICALLY MEANINGFUL BASES" in Paris, May 1995. This proposal has principally been based on the present project by the head investigator.
