The influence of shielding on the Shannon information entropy for atomic states in strong coupled plasma is investigated using the perturbation method and the Ritz variational method. The analytic expressions for the Shannon information entropies of the ground (1s) and the first excited states (2p) are derived as functions of the ion-sphere radius including the radial and angular parts. It is shown that the entropy change in the atomic state is found to be more significant in the excite state than in the ground state. It is also found that the influence of the localization on the entropy change is more significant for an ion with a higher charge number. The variation of the 1s and 2p Shannon information entropies are discussed.

强耦合等离子体中原子态香农信息熵的特征

使用微扰法和Ritz变分法研究了屏蔽对强耦合等离子体中原子态香农信息熵的影响。地面 (1s) 和第一激发态 (2p) 的香农信息熵的解析表达式被推导出为离子球半径的函数，包括径向和角度部分。结果表明，原子态的熵变化在激发态比在基态更显着。还发现对于具有较高电荷数的离子，局域化对熵变的影响更显着。讨论了1s和2p香农信息熵的变化。
