论文摘要
为了研究偶极激发，提出了一种具有变形$β$约束的反对称分子动力学（AMD）框架中$ k $投影后的新变化方法。该方法应用于$^{10} $ be和$^{16} $ O来描述低能偶极激发，并发现是偶极激发的有用且经济的方法。在$^{10} $的应用程序中，描述了低能区域的两个偶极状态。对于$^{16} $ O，获得了$ 1_1^ - $和$ 1_2^ - $状态具有显着的偶极优势。 $ 1_1^ - $状态的特征是明显的环形偶极子（TD）和压缩偶极强度，而$ 1_2^ - $具有明显的TD强度，并显示出开发的$α+ {}^{16}^{16} $ o群集结构。通过分析偶极转换的当前密度，讨论了$^{16} $ O中的偶极属性。
For study of dipole excitations, a new method of variation after $K$-projection in the framework of antisymmetrized molecular dynamics (AMD) with the deformation $β$ constraint was proposed. The method was applied to $^{10}$Be and $^{16}$O to describe low-energy dipole excitations and found to be a useful and economical approach for dipole excitations. In the application to $^{10}$Be, two dipole states in low-energy region were described. For $^{16}$O, the $1_1^-$ and $1_2^-$ states with remarkable dipole strengths were obtained. The $1_1^-$ state is characterized by significant toroidal dipole (TD) and compressional dipole strengths, whereas the $1_2^-$ has significant TD strength and shows a developed $α+ {}^{16}$O cluster structure. Dipole properties in $^{16}$O were discussed by analysis of current densities of the dipole transitions.
