In almost all of the cases studied, our results agree well with the positions and heights of the experimental peaks.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Atomic, molecular and optical physicsPhysical sciencesIonization of atoms through positron impactDistorted-wave Born approximationTriple-differential cross-sectionsArticle
