Ultrafast photoelectron spectroscopy of photoexcited aqueous ferrioxalate

Majed Chergui, Michele Puppin, Frank van Mourik, Christopher Alexander Arrell, José Javier Pancracio Ojeda Andara, Luca Longetti, Thomas Roland Barillot

The photochemistry of metal-organic compounds in solution is determined by both intra- and inter-molecular relaxation processes after photoexcitation. Understanding its prime mechanisms is crucial to optimise the reactive paths and control their outcome. H ...

A compact and cost-effective hard X-ray free-electron laser driven by a high-brightness and low-energy electron beam

Majed Chergui, Leonid Rivkin, Giulia Fulvia Mancini, Rasmus Ischebeck, Camila Bacellar Cases Da Silveira, Mike Seidel, Christoph Peter Hauri, Paul Beaud, Christopher Alexander Arrell, Eugenio Ferrari

We present the first lasing results of SwissFEL, a hard X-ray free-electron laser (FEL) that recently came into operation at the Paul Scherrer Institute in Switzerland. SwissFEL is a very stable, compact and cost-effective X-ray FEL facility driven by a lo ...

Photoemission from non-polar aromatic molecules in the gas and liquid phase

Majed Chergui, Frank van Mourik, Christopher Alexander Arrell, Lars-Hendrik Mewes, José Javier Pancracio Ojeda Andara, Jakob Grilj, Luca Longetti

The photoelectron spectra of both liquid and gas phase aromatic molecules are reported. The spectra were obtained using a 34.1 eV source produced by high harmonic generation and analysed with the help of high-level ab initio simulations using the reflectio ...
