摘　　要：原子核是由有限多核子构成的自束缚体系.研究原子核的共振态,一方面能得到原子核壳层结构、形状、软硬等性质;另一方面还能理解宇宙中元素的形成和演化的信息.由于原子核的共振态由原子核内的核子-核子相互作用决定,研究原子核的共振态还能获得核子-核子相互作用的信息,并检验各种理论模型是否合理.介绍原子核的各类共振态和它们在核物理和天体核物理中的作用,以及密度泛函相关的理论对共振态的研究现状.Nulcei are systems composed of finite numbers of nucleons by self-binding.Researches on the nuclear resonances states could yield microscopically the proterties of nuclei such as shell structures,shapes,and incompressibilities.On the other hand,it is helpful to understand the synthesis and evolution information of elements macroscopically in the universe.Moreover,it is applied to extract the information of the nucleon-nucleon interaction as the resonances are determined by the interaction,and to check if the various models are reasonable or not.This article is written to introduce briefly various resonances of nuclei,their roles played in the nuclear physics and astrophysics,and the research status of these states based on the density functional theory.
