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…

Spectroscopically resolved resonant interatomic Coulombic decay in photoexcited large He nanodroplets

L. Ben Ltaief, K. Sishodia, R. Richter +8

Interatomic Coulombic decay (ICD) processes play a crucial role in weakly bound complexes exposed to intense or high-energy radiation. Using large helium nanodroplets, we demonstra…

Coincident angle-resolved state-selective photoelectron spectroscopy of acetylene molecules: a candidate system for time-resolved dynamics

Suddhasattwa Mandal, Ram Gopal, Hemkumar Srinivas +9

The acetylene-vinylidene system serves as a benchmark for investigations of ultrafast dynamical processes where the coupling of the electronic and nuclear degrees of freedom provid…

Direct inner-shell photoionization of Xe atoms embedded in helium nanodroplets

Ltaief Ben Ltaief, Mykola Shcherbinin, Suddhasattwa Mandal +4

We present the first measurements of photoelectron spectra of atomic clusters embedded in superfluid helium (He) nanodroplets. Owing to the large absorption cross section of xenon…

Charge-exchange dominates long-range interatomic Coulombic decay of excited metal-doped He nanodroplets

L. Ben Ltaief, M. Shcherbinin, S. Mandal +9

Atoms and molecules attached to rare gas clusters are ionized by an interatomic autoionization process traditionally termed 'Penning ionization' when the host cluster is resonantly…
