氟里昂-22过热液滴的中子探测效率
Efficiency of neutron detection of superheated drops of Freon-22
摘要：
本文报道了氟里昂22过热液滴对3Ci Am-Be中子源中子的探测效率。用本实验室研制的体积法从核化率测量值中测定了F-22和F-12的中子探测效率。结果表明，对于Am-Be源的特定中子注量率，F-22对Am-Be能谱的中子探测效率几乎是F-12的两倍，而寿命比F-12小58.6%。
英文摘要：
Neutron detection efficiency of superheated drops of Freon22 for neutrons obtained from a 3Ci Am-Be neutron source has been reported in this paper. Neutron detection efficiency of both F-22 and F-12 have been determined from the measured nucleation rate using the volumetric method developed in our lab. The result shows that the neutron detection efficiency of F-22 for the energy spectrum obtained from Am-Be is almost double, while the life time is 58.6% smaller than that of F-12, for a particular neutron flux of that source.
