Interatomic or intermolecular Coulombic decay (ICD) is a nonlocal electronic decay
mechanism occurring in weakly bound matter. In an ICD process, energy released by …

Abstract Short wavelength Free-Electron Lasers (FELs) are among the newest light sources
available to scientists to probe a wide range of phenomena, with chemical, physical and …

X-ray free-electron lasers (XFELs) made available a new regime of x-ray intensities,
revolutionizing the ultrafast structure determination and laying the foundations of the novel …

Ionization of matter by energetic radiation generally causes complex secondary reactions
that are hard to decipher. Using large helium nanodroplets irradiated by extreme ultraviolet …

We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a
weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. In …

The intensity-difference spectrum technique is applied to record charge-state resolved ion
energy spectra from the Coulomb explosion of small Ar clusters under well-resolved laser …

Irradiation of nanoscale clusters and large molecules with intense laser pulses transforms
them into highly-excited non-equilibrium states. The dynamics of intense laser-cluster …

Using electron and ion spectroscopy, we studied the electron and nuclear dynamics in∼ 50
000-atom large krypton clusters, following excitation with an intense hard x-ray pulse …

The long-time correlated decay dynamics of strong-field exposed helium nanodroplets is
studied by means of photoelectron spectroscopy. As a result of the adiabatic expansion of …

Femtosecond pump-probe electron and ion spectroscopy is applied to study the
development of a helium nanoplasma up to the nanosecond timescale. Electrons, bound by …
