Title: Comparison of Lu<sub>0.7</sub>Y<sub>0.3</sub>AP:Ce and Bi<sub>4</sub>Ge<sub>3</sub>O<sub>12</sub> Scintillators in Gamma Ray Spectrometry
Abstract: The scintillation response of Lu 0.7 Y 0.3 AP:Ce and Bi 4 Ge 3 O 12 scintillation crystals have been compared using photomultiplier tube readout for photon energies ranging from 22.1 to 1274.5 keV. Lu 0.7 Y 0.3 AP:Ce showed a light yield non-proportionality of about 20% upon lowering energy from 1,274.5 to 22.1 keV, which is better than that of about 39% obtained for Bi 4 Ge 3 O 12 . Lu 0.7 Y 0.3 AP:Ce showed the light yield of 13,400 ph/MeV and energy resolution of about 8 % for 662 keV gamma rays from a 137 Cs source. The photofraction of Bi 4 Ge 3 O 12 is better than that of Lu 0.7 Y 0.3 AP:Ce. The intrinsic resolution of the crystals versus energy of gamma rays has been determined after correcting the measured energy resolution for photomultiplier tube statistics.
