Fig. 8From: Coincidence energy spectra due to the intrinsic radioactivity of LYSO scintillation crystalsNormalized count rate for two opposing LYSO scintillation crystals of dimensions 57.4 × 57.4 × 10 mm3 as a function of d. Note that for the experimental count rate more separation distances were included for completeness. Experimental uncertainties for the detector separation distance are smaller than the symbol size.Back to article page
