X-ray photoelectron spectroscopy of Ar and Kr clusters formed in He nanodroplets

N. S. Blaj, N. Scheel, R. Rajni +7

We report the first soft x-ray photoelectron spectroscopy (XPS) measurements of Ar and Kr clusters formed inside superfluid helium nanodroplets (HNDs) through consecutive pickup of…

Valence Ionization Of Water Clusters Formed Inside Helium Nanodroplets

Subhendu De, Sivarama Krishnan, Niklas Sheel +5

The ionization mechanisms of small HO/DO clusters embedded in helium nanodroplets (HNDs) irradiated with extreme ultraviolet photons of energy = 21.6 eV are investigat…

Dichography: Two-frame Ultrafast Imaging from a Single Diffraction Pattern

Linos Hecht, Andre Al Haddad, Björn Bastian +47

We experimentally demonstrate that pairs of time-delayed ultrabright and ultrashort X-ray pulses of two different colors, delivered by modern X-ray Free Electron Lasers, can provid…

Model-free pattern separation of two-color ultrafast X-ray diffraction

Linos Hecht, Yevheniy Ovcharenko, Asbjørn Ø. Lægdsmand +28

Two-color X-ray imaging with Free Electron Laser pulses offers a powerful approach for probing ultrafast structural dynamics in nanoscale systems, combining (near-)atomic spatial r…

Relaxation dynamics in excited helium nanodroplets probed with high resolution, time-resolved photoelectron spectroscopy

A. C. LaForge, J. D. Asmussen, B. Bastian +18

Superfluid helium nanodroplets are often considered as transparent and chemically inert nanometer-sized cryo-matrices for high-resolution or time-resolved spectroscopy of embedded…

Observation of sequential three-body dissociation of camphor molecule -- a native frame approach

S. De, S. Mandal, Sanket Sen +11

The three-body dissociation dynamics of the dicationic camphor molecule (CHO) resulting from Auger decay are investigated using soft X-ray synchrotron radiatio…
