Transition probability functions for inelastic electron--electron scattering
Stefan Löffler, Peter Schattschneider
In this work, the transition matrix elements for inelastic electron--electron scattering are investigated. The angular part is given by spherical harmonics. For the weighted radial…
Electron vortices in crystals
Stefan Löffler, Peter Schattschneider
The propagation of electron beams carrying angular momentum in crystals is studied using a multislice approach for the model system Fe. It is found that the vortex beam is distorte…
Sub-nanometer free electrons with topological charge
P. Schattschneider, M. Stöger-Pollach, S. Löffler +3
The holographic mask technique is used to create freely moving electrons with quantized angular momentum. With electron optical elements they can be focused to vortices with diamet…
