EFFECT OF SCATTERED RADIATION OF THE SHAPE OF THE INSTRUMENTAL LINE OF A SCINTILLATION GAMMA SPECTROMETER

摘要

In detecting monoenergetic γ rays, the instrumental line of the scintillation spectrometer consists of a photopeak cor- responding to the photons absorbed in the crystal and a wide distribution due to photons which were scattered in the detector and left the detector losing only a part of their energy [1]. Ordinarily, the energy of the primary photons is judged according to the position of a photopeak.
