Wavelength-Dependent Photodissociation of Iodomethylbutane

Valerija Music, Felix Allum, Ludger Inhester +37

Ultrashort XUV pulses of the Free-Electron-LASer in Hamburg (FLASH) were used to investigate laser-induced fragmentation patterns of the prototypical chiral molecule 1-iodo-2-methy…

Melting, bubble-like expansion and explosion of superheated plasmonic nanoparticles

Simon Dold, Thomas Reichenbach, Alessandro Colombo +32

We report on time-resolved coherent diffraction imaging of gas-phase silver nanoparticles, strongly heated via their plasmon resonance. The x-ray diffraction images reveal a broad…

Three-Dimensional Coherent Diffractive Imaging of Isolated Faceted Nanostructures

Alessandro Colombo, Simon Dold, Patrice Kolb +29

The structure and dynamics of isolated nanosamples in free flight can be directly visualized via single-shot coherent diffractive imaging using the intense and short pulses of X-ra…

The Kinetic Energy of PAH Dication and Trication Dissociation Determined by Recoil-Frame Covariance Map Imaging

Jason W. L. Lee, Denis S. Tikhonov, Felix Allum +28

We investigated the dissociation of dications and trications of three polycyclic aromatic hydrocarbons (PAHs), fluorene, phenanthrene, and pyrene. PAHs are a family of molecules ub…

Ultrafast MHz-rate burst-mode pump-probe laser for the FLASH FEL facility based on nonlinear compression of ps-level pulses from an Yb-amplifier chain

Marcus Seidel, Federico Pressacco, Oender Akcaalan +24

The Free-Electron Laser (FEL) FLASH offers the worldwide still unique capability to study ultrafast processes with high-flux, high-repetition rate XUV and soft X-ray pulses. The va…

Following excited-state chemical shifts in molecular ultrafast x-ray photoelectron spectroscopy

Dennis Mayer, Fabiano Lever, David Picconi +17

The conversion of photon energy into other energetic forms in molecules is accompanied by charge moving on ultrafast timescales. We directly observe the charge motion at a specific…
