Multi-electron dynamics in atoms and molecules very often occur on sub-to few-femtosecond
time scales. The available intensities of extreme-ultraviolet (XUV) attosecond pulses have …

Two-XUV-photon double ionization of Ne, induced by an intense few-pulse attosecond train
with a∼ 4 fs envelope duration is investigated experimentally and theoretically. The …

New information demonstrating the importance of both sequential and simultaneous (or
direct) multiphoton ionization of inner shell electrons from neon is discussed in this paper …

The dichroism effects, ie, asymmetries of the ionization probability with respect to the
inversion of either the atomic orientation (magnetic dichroism, MD) or the circular …

The formation and decay of double-core-hole (DCH) states of the neon ion irradiated by an
intense electromagnetic x-ray field are studied theoretically. In the present research DCH …

When high-energy pulses interact with atoms or molecules, they ionise inner electrons
leaving the system in an unstable state. Following such ionisations, the system decays via …

Free-Electron Lasers (FEL) are new Light Sources which are promising to bring a revolution
in our understanding of electron and nuclear dynamics inside driven complex molecules …
