论文摘要
目前的理论工作介绍了在单个电荷交换反应中形成阳性抗溶质离子的研究，其中正电子（地面或激发态）与基态抗氢原子相互作用，并嵌入密集的Debye血浆中。计算是在库仑扭曲的艾科尼尔近似的框架工作中进行的。结果表明，PS（3S）是在接近反应阈值的能量下增强抗H^+产生的最有趣状态。关于Debye筛选，可以推断在较低的能量状态下，筛选效果增强了1S和2S状态的TC，而PS的2P和3S状态则降低了。
The present theoretical work addresses the study of the formation of a positive Antihydrogen ion in a single charge exchange reaction where a positronium ( ground or excited state) interacts with a ground state anti-hydrogen atom, being embedded in a dense Debye plasma. The calculations are carried out in the frame work of a Coulomb Distorted Eikonal Approximation. The result shows that Ps(3S) is the most interesting state to enhance the anti H^+ production at the energy close to the reaction threshold. Regarding the Debye screening, it may be inferred that in lower energy regime, the screening effect enhances the TCS for the 1S and 2S states while reduces the same for the 2P and 3S states of Ps.
