We present experiments on field-free molecular alignment of N2 and CO2 probed with short XUV pulses that are obtained via high-harmonic generation. The XUV pulses induce a dissociative ionization or a Coulomb explosion of the molecule, where the frag

Observation of correlated electronic decay in expanding clusters triggered by near-infrared fields

Autor: Bernd Schütte, Alexander I. Kuleff, Mathias Arbeiter, Marcus Vrakking, Thomas Fennel, G. Jabbari, Arnaud Rouzée

Publikováno v: Nature Communications

When an excited atom is embedded into an environment, novel relaxation pathways can emerge that are absent for isolated atoms. A well-known example is interatomic Coulombic decay, where an excited atom relaxes by transferring its excess energy to ano

Highly excited molecular species are at play in the chemistry of interstellar media and are involved in the creation of radiation damage in a biological tissue. Recently developed ultrashort extreme ultraviolet light sources offer the high excitation

Recombination dynamics of clusters in intense extreme-ultraviolet and near- infrared fields

Autor: Maria Krikunova, Bernd Schütte, Tim Oelze, Mathias Arbeiter, Marcus Vrakking, Thomas Fennel, Arnaud Rouzée

We investigate electron-ion recombination processes in clusters exposed to intense extreme-ultraviolet (XUV) or near-infrared (NIR) pulses. Using the technique of reionization of excited atoms from recombination (REAR), recently introduced in Schütt

International audience; In nonhydrogenic atoms in a dc electric field, the finite size of the ionic core introduces a coupling between quasibound Stark states that leads to avoided crossings between states that would otherwise cross. Near an avoided

Publikováno v: Science. 312:246-248

We demonstrated how the subcycle evolution of the electric field of light can be used to control the motion of bound electrons. Results are presented for the dissociative ionization of deuterium molecules (D 2 ⇒ D + + D), where asymmetric ejection

We discuss how a recent pump-probe study [Kelkensberg et al., Phys. Rev. Lett. 103, 123005 (2009)] of the dissociative ionization of H2, under the combined effect of a single extreme ultraviolet attosecond pulse and an intense near- infrared pulse, a
