Coulomb-explosion imaging of concurrent CH$_{2}$BrI photodissociation dynamics
ddc:530
The dynamics following laser-induced molecular photodissociation of gas-phase CH$_{2}$BrI at 271.6 nm were investigated by time-resolved Coulomb-explosion imaging using intense near-IR femtosecond laser pulses. The observed delay-dependent photofragment momenta reveal that CH$_{2}$BrI undergoes C-I cleavage, depositing 65.6% of the available energy into internal product states, and that absorption of a second UV photon breaks the C-Br bond ofCH$_{2}$Br.

Time-Resolved Measurement of Interatomic Coulombic Decay Induced by Two-Photon Double Excitation of Ne 2
ddc:550
The hitherto unexplored two-photon doubly excited states [Ne*$(2p−^13s)]_2$ were experimentallyidentified using the seeded, fully coherent, intense extreme ultraviolet free-electron laser FERMI. Thesestates undergo ultrafast interatomic Coulombic decay (ICD), which predominantly produces singly ionizeddimers. [...]

Slow Interatomic Coulombic Decay of Multiply Excited Neon Clusters
ddc:550
Ne clusters (∼5000 atoms) were resonantly excited $(2p→3s)$ by intense free electron laser (FEL)radiation at FERMI. Such multiply excited clusters can decay nonradiatively via energy exchange betweenat least two neighboring excited atoms. [...]

Mix-and-diffuse serial synchrotron crystallography
IUCrJ 4(6), 769 - 777 (2017) [10.1107/S2052252517013124]  GO
ddc:530
Unravelling the interaction of biological macromolecules with ligands and substrates at high spatial and temporal resolution remains a major challenge in structural biology. The development of serial crystallography methods at X-ray free-electron lasers and subsequently at synchrotron light sources allows new approaches to tackle this challenge. [...]

Attosecond chronoscopy of electron scattering in dielectric nanoparticles
Nature physics 13(8), 766 - 770 (2017) [10.1038/nphys4129]  GO
ddc:530
The scattering of electrons in dielectric materials is central to laser nanomachining$^1$, light-driven electronics$^2$ and radiation damage$^{3, 4, 5}$. Here, we demonstrate real-time access to electron scattering by implementing attosecond streaking spectroscopy on dielectric nanoparticles: photoelectrons are generated inside the nanoparticles and both their transport through the material and photoemission are tracked on an attosecond timescale [...]

Alignment, Orientation, and Coulomb Explosion of Difluoroiodobenzene Studied with the Pixel Imaging Mass Spectrometry (PImMS) Camera
[arXiv:1706.08376] ddc:540
Laser-induced adiabatic alignment and mixed-field orientation of 2,6-difluoroiodobenzene (C$_6$H$_3$F$_2$I) molecules are probed by Coulomb explosion imaging following either near-infrared strong-field ionization or extreme-ultraviolet multi-photon inner-shell ionization using free-electron laser pulses. The resulting photoelectrons and fragment ions are captured by a double-sided velocity map imaging spectrometer and projected onto two position-sensitive detectors. [...]

Jitter-correction for IR/UV-XUV pump-probe experiments at the FLASH free-electron laser
ddc:530
In pump-probe experiments employing a free-electron laser (FEL) in combination with a synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the optical laser pulse often severely limits the temporal resolution that can be achieved. Here, we present a pump-probe experiment on the UV-induced dissociation of 2,6-difluoroiodobenzene $(C_{6}H_{3}F_{2}I)$ molecules performed at the FLASH FEL that takes advantage of recent upgrades of the FLASH timing and synchronization system to obtain high-quality data that are not limited by the FEL arrival-time jitter.
