This work presents the calculations of differential, integrated elastic and momentum transfer cross sections for the elastic scattering of electrons from the ions of xenon isonuclear series over the incident energy range 1 eV–1000 eV. Coulomb glory, the amplification of elastic backscattering of electrons from positive ions owing to the electrostatic screening of nuclear potential by atomic electrons, is investigated throughout the ionic series of xenon, argon and neon. Cross sections for the angular distribution of elastically scattered positron from selected xenon ions are also calculated. Energy dependency of differential cross sections and Sherman functions are predicted for both the projectiles and a comparison is presented to exhibit the dissimilarity arising out of the difference of the interactions of the projectiles with ions. The theoretical methodology of this work employs the Dirac relativistic partial wave analysis using a complex optical potential, comprising static, exchange, polarization and imaginary components, and a pure Coulomb potential. The results obtained show reasonable agreements with the available experimental data and other theoretical calculations.

这项工作介绍了在入射能量范围1 eV–1000 eV下，氙异核系列离子的电子弹性散射的微分，积分弹性和动量传递截面的计算。在整个氙，氩和氖离子系列中，研究了库仑的荣耀，这是由于原子电子对核势的静电屏蔽而导致的正离子对电子的弹性反向散射的放大。还计算了来自选定的氙离子的弹性散射正电子的角度分布的横截面。预测了两种弹丸的微分截面和谢尔曼函数的能量依赖性，并进行了比较，以显示弹丸与离子相互作用的差异引起的不相似性。这项工作的理论方法是使用狄拉克相对论分波分析方法，该方法使用了复杂的光势，包括静态，交换，极化和虚构分量以及纯库仑势。获得的结果表明与可用的实验数据和其他理论计算有合理的一致性。
