Quantum mechanical calculations have been accomplished to study the dynamics of the reaction: p + H(1s) → H(nlm) + p in dense semi‐classical hydrogen plasma. Interactions among the charged particles in plasma are represented by a pseudopotential which takes care of the collective effects at large distances and quantum effect of diffraction at small distances. Various capture cross sections are computed for the incident proton energy lying within 10 to 500 keV by applying a distorted wave method which uses a variationally determined closed‐form wave function of hydrogen atom. Moreover, an inclusive study is made to explore the effects of screening of plasma and quantum diffraction on various capture cross sections for a wide range of thermal Debye length and de Broglie wave length. It has been found that various cross sections suffer considerable changes due to varying Debye length and de Broglie wave length.

致密半经典氢等离子体中质子氢碰撞中的电子转移

已经完成了量子力学计算，以研究反应的动力学：p  +  H（1 s）→  H（nlm）+  p在致密的半经典氢等离子体中 等离子体中带电粒子之间的相互作用由伪电位表示，该伪电位负责大距离处的集体效应和小距离处的衍射量子效应。通过应用畸变波方法计算入射角在10到500 keV之内的质子能量的各种俘获截面，该方法使用变化确定的氢原子闭式波函数。此外，进行了一项包容性研究，以探讨在宽的热德拜长度和德布罗意波长的范围内，等离子体筛查和量子衍射对各种捕获截面的影响。已经发现，由于变化的德拜长度和德布罗意波的波长，各种横截面遭受相当大的变化。
