论文摘要
我们将相对论配置互动（CI）框架应用于稳定方法，以作为获得氦气样离子的自由离子共振结构的一种方法。在这种方法中，离子限制在无法穿透的球形腔内，其大小决定了可用于电子波形和电子电子相互作用的径向空间。通过改变腔体的大小，可以获得自由离子共振位置和宽度。在与文献中可用的基准数据进行比较的同时，测试了该方法的适用性。目前的方法进一步应用于确定氦样铀离子的共振结构，在该结构中，相对论框架是强制性的。在强量区域中，目前的方法对于在极压下模拟原子或离子的性质很有用。简要讨论了当前方法来确定嵌入在致密等离子体环境中的离子结构的示例应用。
We applied a relativistic configuration-interaction (CI) framework to the stabilization method as an approach for obtaining the autoionization resonance structure of heliumlike ions. In this method, the ion is confined within an impenetrable spherical cavity, the size of which determines the radial space available for electron wavefunctions and electron-electron interactions. By varying the size of the cavity, one can obtain the autoionization resonance position and width. The applicability of this method is tested on the resonances of He atom while comparing with benchmark data available in the literature. The present method is further applied to the determination of the resonance structure of heliumlike uranium ion, where a relativistic framework is mandatory. In the strong-confinement region, the present method can be useful to simulate the properties of an atom or ion under extreme pressure. An exemplary application of the present method to determine the structure of ions embedded in a dense plasma environment is briefly discussed.
