Since Olson [Phys. Rev. A 33, 4397 (1986) 0556-2791 10.1103/PhysRevA. 33.4397] …

Controlling electron projectile coherence effects using twisted electrons

AL Harris - Physical Review A, 2023 - APS
In traditional scattering theory, the incident projectile is assumed to have an infinite
coherence length. However, over the last decade, experimental and theoretical studies of …

Projectile Coherence Effects in Twisted Electron Ionization of Helium

AL Harris - Atoms, 2023 - mdpi.com
Over the last decade, it has become clear that for heavy ion projectiles, the projectile's
transverse coherence length must be considered in theoretical models. While traditional …
