Proceedings ArticleDOI
Recoil ion momentum spectroscopy a 'momentum microscope' to view atomic collision dynamics
Reinhard Dörner,V. Mergel,H. Bräuning,M. Achler,Thorsten Weber,Kh. Khayyat,Ottmar Jagutzki,Lutz Spielberger,Joachim Ullrich,R. Moshammer,Yoshiro Azuma,M. H. Prior,C. L. Cocke,Horst Schmidt-Böcking +13 more
TL;DR: In this paper, photo double ionization of helium by linear and circular polarized light is discussed and a 4 π solid angle is used to measure the three dimensional momentum vector of the ion from those reactions.
Journal ArticleDOI
Double and Single Ionization of Helium by 58-keV X Rays
Lutz Spielberger,Ottmar Jagutzki,B. Krässig,U. Meyer,Kh. Khayyat,V. Mergel,Th. Tschentscher,Th. Buslaps,H. Bräuning,Reinhard Dörner,T. Vogt,M. Achler,J. Ullrich,D. S. Gemmell,Horst Schmidt-Böcking +14 more
TL;DR: The ratio of cross sections for double to single ionization of helium by Compton scattering is measured using cold target recoil ion momentum spectroscopy and is in agreement with the asymptotic limits predicted by Andersson and Burgd and Suri.
Journal ArticleDOI
Photo double ionization of He by circular and linear polarized single-photon absorption
TL;DR: In this article, the authors measured absolute fully differential cross sections for photo double ionization of helium by circularly and linearly polarized light 20 eV above threshold and showed fivefold differential cross-sections.
Journal ArticleDOI
Cross-section ratio of double to single ionization of helium by compton scattering of 40-100-kev x rays
Lutz Spielberger,H. Bräuning,A. Muthig,J. Z. Tang,Ji-Guang Wang,Yanghui Qiu,Reinhard Dörner,Ottmar Jagutzki,Th. Tschentscher,Veijo Honkimäki,V. Mergel,M. Achler,Th. Weber,Kh. Khayyat,J. Burgdörfer,James H. McGuire,H. Schmidt-Böcking +16 more
TL;DR: In this paper, the authors measured the ratio of cross sections for double to single ionization of helium by Compton scattering at photon energies of 40, 80, and 100 keV using cold target recoil-ion momentum spectroscopy.
Journal ArticleDOI
A design study for an internal gas-jet target for the heavy-ion storage ring CRYRING
Henning T. Schmidt,Henrik Cederquist,R. Schuch,L. Bagge,Anders Källberg,J. Hilke,K.-G. Rensfelt,V. Mergel,M. Achler,Reinhard Dörner,Lutz Spielberger,Ottmar Jagutzki,Horst Schmidt-Böcking,Joachim Ullrich,H. Reich,M. Unverzagt,W. Schmitt,R. Moshammer +17 more
TL;DR: In this paper, the internal gas-jet target, CRYJET, was constructed for investigations of fast ion-atom collisions in the heavy-ion storage and cooler ring CRYRING at the Manne Siegbahn Laboratory, Stockholm University.
