Isotope effects in dynamics of water isotopologues induced by core ionization at an x-ray free-electron laser

R. Guillemin, L. Inhester et al.

Dynamical response of water exposed to x-rays is of utmost importance in a wealth of science areas. We exposed isolated water isotopologues to short x-ray pulses from a free-electron laser and ...

Nonequilibrium warm dense matter investigated with laser–plasma-based XANES down to the femtosecond

F. Dorchies, K. Ta Phuoc et al.

The use of laser–plasma-based x-ray sources is discussed, with a view to carrying out time-resolved x-ray absorption spectroscopy measurements, down to the femtosecond timescale. A review of recent ...
