Ultrafast photoelectron spectroscopy of solutions: space-charge effect

open access: yesNew Journal of Physics, 2015
The method of time-resolved XUV photoelectron spectroscopy is applied in a pump–probe experiment on a liquid micro-jet. We investigate how the XUV energy spectra of photoelectrons are influenced by the space charge created due to ionization of the liquid

Time-Resolved Photoelectron Spectroscopy of Coupled Nuclear-Electronic Dynamics

open access: yesEPJ Web of Conferences, 2013
We study the effect of nuclear-electron coupling on time-resolved photo-electron spectra, employing a model system which allows to directly comparing spectra resulting from the adiabatic approximation with those obtained within a non-Born-Oppenheimer ...

Photoelectron spectroscopy of NpPd3 and PuPd3 [PDF]

open access: yes, 2008
We present the results of x-ray and ultraviolet photoelectron spectroscopy of NpPd3 and PuPd3. The spectra indicate that for both compounds, the 5f electrons are well localized on the actinide sites.

Recent advances in experimental techniques to probe fast excited-state dynamics in biological molecules in the gas phase : dynamics in nucleotides, amino acids and beyond [PDF]

open access: yes, 2013
In many chemical reactions, an activation barrier must be overcome before a chemical transformation can occur. As such, understanding the behaviour of molecules in energetically excited states is critical to understanding the chemical changes that these ...

Liquid-microjet photoelectron spectroscopy of the green fluorescent protein chromophore

open access: yesNature Communications, 2022
The electronic structures of photoactive proteins underlie many natural photoinduced processes. The authors, using UV liquid-microjet photoelectron spectroscopy and quantum chemistry calculations, determine electron detachment energies of the green ...

Following the relaxation dynamics of photoexcited aniline in the 273-266 nm region using time-resolved photoelectron imaging [PDF]

open access: yes, 2013
Scanning tunnelling microscopy (STM) and Auger electron spectroscopy (AES) have been used to investigate the growth morphology of ultra-thin Pb films on the Ni3Al(111) face at room temperature. A previous study [K. Miśków and A. Krupski Appl Surf Sci 273,
