Journal ArticleDOI
Electron Localization in Molecular Fragmentation of H-2 by Carrier-Envelope Phase Stabilized Laser Pulses
M. Kremer,B. Fischer,Bernold Feuerstein,Vitor Luiz Bastos de Jesus,Vandana Sharma,Christian Hofrichter,Artem Rudenko,Uwe Thumm,Claus Dieter Schröter,Robert Moshammer,Joachim Ullrich +10 more
TL;DR: Wave packet propagation calculations reproduce the salient features and discard, together with the observed KER-independent electron asymmetry, the first ionization step to be the reason for the asymmetric proton emission.
Journal ArticleDOI
Observing the creation of electronic feshbach resonances in soft x-ray-induced O2 dissociation.
Arvinder Sandhu,Etienne Gagnon,Robin Santra,Robin Santra,Vandana Sharma,Wen Li,Phay J. Ho,Predrag Ranitovic,C. Lewis Cocke,Margaret M. Murnane,Henry C. Kapteyn +10 more
TL;DR: It is found that autoionization after soft x-ray photoionization of molecular oxygen follows a complex multistep process and states with negative binding energies have not previously been predicted or observed in neutral atoms.
Journal ArticleDOI
Steering the electron in H2+ by nuclear wave packet dynamics
B. Fischer,M. Kremer,Thomas Pfeifer,Bernold Feuerstein,Vandana Sharma,Uwe Thumm,Claus Dieter Schröter,Robert Moshammer,Joachim Ullrich +8 more
TL;DR: By combining carrier-envelope phase (CEP) stable light fields and the traditional method of optical pump-probe spectroscopy, this article studied electron localization in dissociating H{sub 2}{sup +} molecular ions.
Journal ArticleDOI
Direct measurement of the angular dependence of the single-photon ionization of aligned N2 and CO2.
Isabell Thomann,Robynne M. Lock,Vandana Sharma,Etienne Gagnon,Stephen T. Pratt,Henry C. Kapteyn,Margaret Murnane,Wen Li +7 more
TL;DR: The data show that the transition dipoles for single-photon ionization of N2 and CO2 at 43 eV have larger perpendicular components than parallel ones, which provides the first step toward a novel method for measuring molecular frame transition dipole matrix elements.
Journal ArticleDOI
Attosecond Correlated Dynamics of Two Electrons Passing through a Transition State
Nicolas Camus,B. Fischer,M. Kremer,Vandana Sharma,Artem Rudenko,Boris Bergues,Matthias Kübel,Nora G. Johnson,Matthias F. Kling,Thomas Pfeifer,Joachim Ullrich,R. Moshammer +11 more
TL;DR: The strong-field induced decay of a doubly excited, transient Coulomb complex Ar**→Ar(2+)+2e(-) is explored by tracing correlated two-electron emission in nonsequential double ionization of Ar as a function of the carrier-envelope phase.
