摘要： 中子能谱解谱是制约中子能谱测量技术发展的瓶颈。遗传基因算法是人工智能领域一种全局收敛算法。通过探讨遗传基因算法在中子解谱领域的应用，基于遗传基因算法开发了中子能谱解谱程序，在多球谱仪中子能谱测量中取得了较好的结果。利用多球谱仪测量了241Am-Be中子源和252Cf中子源中子能谱，与ISO8529推荐的标准谱进行了比较，验证了遗传基因算法解谱结果的可靠性。

Abstract: The main factor of limiting development of neutron spectrum measuring technique is unfolding procedure.Genetic algorithm is one of artificial intelligent algorithm,which is quickly global convergence.This paper discusses the application of genetic algorithm in the region of neutron spectrum unfolding.We develop an unfolding program based on genetic algorithm,and the good results have been achieved in measurement of multi sphere.241Am-Be neutron source and 252Cf neutron source were measured by Bonner Sphere Spectrometer(BSS)using genetic algorithm.Compared with the standard spectrum recommended by ISO8529,the reliability of genetic algorithm is verified.

Key words: Neutron spectrum, Genetic algorithm, Few-channel, Unfolding, BSS(Bonner Sphere Spectrometer)
