| Zusammenfassung | We present a theoretical investigation of the radiative recombination of twisted electrons into bound states of initially bare ions. Special emphasis is placed on the magnetic sublevel population of the residual hydrogenlike ions under the assumption that emitted photons remain unobserved. We show that this sublevel population strongly depends on the position of an ion within the incident electron wave front. To better understand this position dependence, detailed calculations are presented for the electron capture into 1s1/2 and 2p3/2 ionic states. The results of the calculations show that the structured beams of hydrogenlike ions can be produced in collisions with Bessel electrons at ion storage rings. Having multiple-ring intensity profiles and complex spin patterns, these structured beams can become a valuable tool for future ion collision studies. |
