论文摘要
在RPA理论的框架内扩展了JOST函数方法，以在表现出复杂的RPA特征素耐药的复杂能平面上找到极点。与RPA激发态相对应的电线杆，例如$^{16} $ o电偶极激发的巨大共振，在复杂的能量平面上成功发现。尽管巨大的共鸣被称为具有较大强度和宽度的单一共鸣，但发现至少在RPA框架内，$^{16} $ o电动偶极巨型巨型共振是由多个电线杆形成的，每一个都是独立的极杆，具有不同的宽度，具有不同的宽度，具有不同的宽度，对残留相互作用的响应，对残留互动和组合结构的响应特性易变。
The Jost function method is extended within the framework of the RPA theory to find poles on the complex energy plane that exhibit complex RPA eigenenergies. Poles corresponding to the RPA excited states such as the giant resonance of $^{16}$O electric dipole excitations were successfully found on the complex energy plane. Although the giant resonance has been known as a single resonance with large strength and width, it is found that, at least within the RPA framework, the $^{16}$O electric dipole giant resonance is formed by multiple poles, each of which is an independent pole with different widths, origins, response properties to residual interactions, and components structures of the density fluctuation.
