Elastic scattering of twisted electrons by an atomic target: Going beyond the Born approximation
Elastic scattering of twisted electrons by an atomic target: Going beyond the Born approximation
The elastic scattering of twisted electrons by neutral atoms is studied within the fully relativistic framework. The electron-atom interaction is taken into account in all orders, thus allowing us to explore high-order effects beyond the first Born approximation. To illustrate these effects, detailed calculations of the total and differential cross …
