摘　　要：原子核的形状共存一直是核物理的研究热点之一。形状共存的研究对于深入理解原子核结构及各种现象具有十分重要的意义。通过协变密度泛函计算了^(322)Cm的位能曲面,并利用五位集体哈密顿量(5DCH)计算了该原子核的激发谱和波函数概率分布。通过对其位能曲面和激发谱的分析,表明^(322)Cm是一个长椭和扁椭共存的原子核。最后对其波函数的概率分布的分析也得出了相同的结论。Shape coexistence of nuclei has always been one of the hot topics in nuclear physics. The study of shape coexistence is very important for understanding the nuclear structure and various phenomena.The collective potential energy surface of^(322)Cm is calculated by means of covariant density functional. The excitation spectrum and wave function probability distribution of the atomic nucleus are calculated by using the microscopic collective Hamiltonian(5DCH). The analysis of its collective potential energy surface and excitation spectrum shows that^(322)Cm is an atomic nucleus with a long ellipse and a flat ellipse. Finally, the analysis of the probability distribution of the wave function also draws the same conclusion.
