Abstract

Abstract: In this work, we report on triply differential ionization cross sections ( e, 2 e ) for atomic and molecular targets, namely, Ar(3 p ), Kr(4 p ), Xe(5 p ) and H2 impacted by twisted electron beams. The calculations were performed within the distorted wave Born approximation by using twisted and distorted waves for describing the incident and outgoing electrons, respectively. We found that the triply differential cross sections were strongly influenced by both the opening angle θ p and the orbital angular momentum OAM number m . Comparisons with experiments as well as existing results were reported.
