摘　　要：中子在核检测应用中发挥着重要的作用,弥补了X射线检测对原子序数不敏感的缺点。在特定能区内,中子反应截面随中子能量剧烈变化,发生共振现象。核素共振能谱具有唯一性,据此可以进行核素的定性和定量分析。其中,中重核的共振能区在eV^keV能区,是中子共振分析中的重要组成部分。目前在该方面已有较多研究成果,在测温、成像、无损分析、核数据测量等方面有较为广泛的应用。对此,通过查阅中子共振方面的文献和书籍,对中子共振国内外的研究状况进行总结和分析,并展望其发展趋势。[Background]Neutrons play an important role in nuclear detection applications,and make up for the shortcomings of X-ray detection insensitivity to the atomic number.In a specific energy range,the cross section of neutron reaction varies drastically with the neutron energy,and resonance occurs.The resonance spectrum of nuclides is unique,and qualitative and quantitative analysis of nuclides can be carried out based on this.Among them,the resonance energy range of medium-heavy nuclei is in the eV^keV energy range,which is an important part of neutron resonance analysis.[Purpose]Due to the lack of conclusive articles on neutron resonance in medium-heavy nuclei,this paper summarizes the current research on neutron resonance.[Methods]By querying a large number of journal papers and books related to neutron resonance,the theory and application of neutron resonance of medium and heavy nuclear are summarized.[Results&Conclusions]At present,there have been many research results,and they have been widely used in temperature measurement,imaging,non-destructive analysis,nuclear data measurement,and other aspects.In this regard,by reviewing the literature and books on neutron resonance,the research status of neutron resonance at domestic and overseas are summarized and analyzed,and its development tendency is forecast.
