Zusammenfassung	We present a theoretical investigation of the inelastic scattering of vortex electrons by many-electron atoms embedded in a solid-state environment. Special emphasis is placed on the probability of exciting a target atom and on the relative population of its magnetic substates as described by the set of alignment parameters. These parameters are directly related to the angular distribution of the subsequent radiative decay. To demonstrate the application of the developed theoretical approach, we present calculations for the 3𝑠2 𝑆01→3𝑠3𝑝 𝑃13 excitation of a Mg atom and its subsequent 3𝑠3𝑝 𝑃13→3𝑠2 𝑆01 radiative decay. Our results highlight the significance of the orbital angular momentum (OAM) projection as well as the relative position of the vortex electron with respect to the target atom.
