Generation of vortex electrons by atomic photoionization
I. Pavlov, A. D. Chaikovskaia, D. V. Karlovets
Abstract
The authors demonstrate the possibility, in principle, to generate photoelectrons with orbital angular momentum using a vortex laser beam in experimentally feasible scenarios; this process can be key to producing high-energy vortex electrons in linear accelerators. They find that the width of the electron wave packet depends on the initial energy of the vortex photon and not on its transverse size.
