现代原子核物理的一个重要领域是对远离β稳定线核素的研究。这些核素都具有短的衰变半衰期。因此,测量短寿命核素或核态衰变的实验技术显得愈益重要。γ射线的多谱分析方法正是这种实验技术的一个组成部分。 早在六十年代中,这种电子学技术随着多道分析器的发展而产生。到七十年代中,多谱分析方法已成为商业性标准多道分析器功能中的一个部分,得到了广泛的应用。目前,则成为在线计算机的一种很普通的数据获取方式。但在国内,至今运用这种技术的报道还不多。 最近,在我所中子发生器实验室建立了跑兔和Ge(Li)探测器γ射线多谱分析方法相结合的实验技术,用以 An important area of ​​modern nuclear physics is the study of radionuclides far from beta-stable lines. These nuclides all have short decay half-lives. Therefore, experimental techniques for measuring short-lived or decaying nuclear states are increasingly important. Multi-spectral analysis of gamma rays is an integral part of this experimental technique. As early as the 1960s, this electronics technology evolved with the development of multiple analyzers. By the seventies, multispectral analysis has become a part of the commercial standard multichannel analyzer and has found wide application. At present, it becomes a very common data acquisition method for online computers. However, in China, there are not many reports on the use of this technology. Recently, an experimental technique was developed in our laboratory for neutron generators to combine the γ-ray multi-spectrum analysis method of running rabbit and Ge (Li) detector.
