摘要
本文叙述了用国产BGO闪烁体构成的用于原子核高自旋态研究的BGO反康普顿高纯锗谱仪的设计和它的性能。测试结果表明,对^(60)Coγ射线源,它的抑制系数在100—500、500—700、700—900keV能区范围内分别为2.8、4.2和5.3。其峰总比为46—49％。
The physical design and characteristics of the BGO-HpGe anti-Compton suppression spectrometers for high spin-state study with home-made BGO scintillators are briefly described. The suppression coefficients are 2.8, 4.2 and 5.3 in the energy region of 100-500, 500-700 and 700-900 keV respectively for 60Co γ-rays. The peak-to-total ratio is about 46-49%.
