论文摘要
我们通过分析计算对称和非对称共面几何形状的第一个诞生近似，在低能量和高能量的亚稳态2S态中氢原子的电子影响电离的三重差分横截面。通过使用相对论的狄拉克形式，研究了该过程，还表明，当使用低入射动能时，非递归主义极限是准确繁殖的。在高能量下，相对论和自旋效应显着影响三重差分横截面。我们的分析方法似乎与非对称共面几何形状的非同性主义方案中的其他结果进行了比较。对于这个特定的过程，在没有任何实验数据和高能的理论模型的情况下，我们无法验证我们的模型。我们希望本研究将为未来的实验做出重大贡献。
We analytically compute, in the first Born approximation for symmetric and asymmetric coplanar geometries, the triple differential cross sections for electron-impact ionization of hydrogen atom in the metastable 2S-state at both low and high energies. The process is investigated by using the relativistic Dirac-formalism and it is also shown that the nonrelativistic limit is accurately reproduced when using low incident kinetic energies. At high energies, relativistic and spin effects significantly affect the triple differential cross sections. Our analytical approach which seems exact is compared to some other results in the nonrelativistic regime for asymmetric coplanar geometry. For this particular process and in the absence of any experimental data and theoretical models at high energies, we are not in a position to validate our model. We hope that the present study will provide significant contribution to future experiments.
