论文摘要
根据扩展的反对称分子动力学计算，我们研究了簇结构以及18O的0+和1-状态。我们讨论了激发光谱中出现了几种不同类型的聚类状态，它们的单极和偶极转变是独特的簇结构的有趣指纹。我们表明，对于14C+α簇状态，单极/偶极转变增强了，而它们则因分子轨道状态而受到阻碍。我们还指出，电和等轴单极过渡强度的比率为激发态的结构提供了良好的提示。
On the basis of an extended antisymmetrized molecular dynamics calculation, we study the cluster structure and the of the 0+ and 1- states of 18O. We discuss that several different kinds of cluster states appear in the excitation spectrum, and their monopole and dipole transitions are interesting fingerprints of unique cluster structure. We show that the monopole/dipole transitions are enhanced for the 14C+alpha cluster states, while they are hindered for the molecular-orbit state. We also point out that the ratio of the electric and isoscalar monopole transition strengths gives a good hint for the structure of the excited states.
