“…Karlovets et al [40] studied the scatterig in the framework of Born approximation. Maiorova et al [41] advanced the scattering studies by their theoretical analysis of the Differential Cross-Section (DCS) for the elastic scattering of twisted electrons by molecular hydrogen H 2 . The angular distribution of the DCS highlighted the influence of the twisted electron beam's parameter on the Young-type interference.…”

In this communication, we present the results of the triple differential cross-section (TDCS) for the (e, 2e) process on H 2 O molecule for the plane wave and the twisted electron beam impact. The formalism is developed in the first Born approximation. We describe the plane/twisted wave, plane wave, the linear combination of atomic orbitals (LCAO) (self-consistent field LCAO method) and Coulomb wave for the incident electron, scattered electron, the molecular state of H 2 O, and the ejected electron, respectively. We investigate the angular profiles of the TDCS for the outer orbitals

We present the angular profiles of the triple differential cross-section (TDCS) for the (e,2e) process on the noble gas atoms, namely He (1s), Ne (2s and 2p), and Ar (3p) for the plane wave and the twisted electron impact. We develop the theoretical formalism in the first-born approximation. The present study compares the TDCS for different values of orbital angular momentum number m and opening angles θ p of the twisted electron beam with that of the plane wave beam. In addition, we also investigate the TDCS for macroscopic atomic targets to explore the influence of opening angle θ p of the twisted electron beam on the TDCS. Our results show that the peaks in binary and recoil region shift from the momentum transfer direction. The results also show that for larger opening angles the peaks for p-type orbitals split into double-peak structures which are not observed in the plane wave results for the given kinematics. The angular profiles for averaged cross-section show the dependence of TDCS on the opening angles which are significantly different from the plane wave TDCS.

“…Such electrons can carry a non-zero projection of the orbital angular momentum (OAM) onto their propagation direction and possess a helical wave front. The angular momentum, as an additional degree of freedom, makes twisted electrons a powerful tool for probing magnetic phenomena in solid-state physics [21,22] and lightmatter coupling [23,24] as well as for studying various atomic scattering processes [25][26][27]. We can expect that OAM-effects will also play an important role in the fundamental process of the radiative recombination and can significantly modify the linear polarization of emitted photons.…”

We present a theoretical investigation of the radiative recombination of twisted Bessel electrons with initially hydrogen-like (finally helium-like) heavy ions. In our study, we focus especially on the linear polarization of x-ray photons emitted in the electron capture into the ground 1s 2 1/2 ionic state. Particular emphasis is placed on the question of how this polarization is affected if incident hydrogen-like ions are themselves spin-polarized. To explore such a "polarization transfer" we apply the density matrix theory and derive the Stokes parameters of recombination x-rays for the realistic case of collisions between macroscopic electron and ion beams. Based on the developed general approach two scenarios are discussed that are of interest for the planned experiments at ion storage rings. First, we demonstrate how the use of twisted electrons can empower the known method for the diagnostics of spin-polarized ion beams, based on the rotation of the linear polarization of recombination light. In the second scenario we show how the internal structure of ions beams with inhomogeneous intensity and spin patterns can be probed by the capture of Bessel electrons, carrying different values of angular momentum.
