Their local physicochemical properties are quite different from those of bulk water and hard to probe experimentally.

We measured the pulse shape of an extremeultraviolet externally seeded FEL operating in high-gain harmonic generation mode.

This process was observed within poly-crystalline diamond with a time-resolved experiment using ultrashort soft x-ray pulses of duration 52.5 fs and cross correlated by an optical pulse of duration 32.8 fs [...] Restricted: PDF PDF (PDFA); 2017-06-0114:22 [PUBDB-2017-04151] Journal Article et al Femtosecond response of polyatomic molecules to ultra-intense hard X-rays Nature 546(7656), 129 - 132 (2017) [10.1038/nature22373]   X-ray free-electron lasers enable the investigation of the structure and dynamics of diverse systems, including atoms, molecules, nanocrystals and single bioparticles, under extreme conditions1, 2, 3, 4, 5, 6, 7. Many imaging applications that target biological systems and complex materials use hard X-ray pulses with extremely high peak intensities (exceeding 1020 watts per square centimetre)3, 5.

Correlation-driven charge migration following double ionization and attosecond transient absorption spectroscopy Physical review / A 95(5), 053411 (2017) [10.1103/PhysRevA.95.053411]   We theoretically investigate charge migration following prompt double ionization. Thereby, we extend the concept of correlation-driven charge migration, which was introduced by Cederbaum and coworkers for single ionization [Chem.

The theoretical foundation of SFI was pioneered in the 1960s, and later refined by various analytical models [...] Restricted: PDF PDF (PDFA); 2017-01-0615:55 [PUBDB-2017-00237] Journal Article Volkov, A.
