The ionization dynamics of Xe cluster was analyzed by extreme ultraviolet (EUV) pump-near infrared (NIR) probe experiments. The experiments were carried out for Xe clusters containing around 5000 atoms on average at the SPring-8 Compact SASE Source (

Unlike metallic elements, rare-gas atoms remain non-metallic even if they are condensed. However, once rare-gas clusters are irradiated by extreme ultraviolet free electron laser (EUV-FEL) pulses with slightly higher energy than their ionization pote

We have developed a dead-time free ion momentum spectroscopy technique that allows us to extract 3D momentum for each of up to 100 ions produced by a single free-electron-laser (FEL) shot, by reading signals from the three-layer delay-line detector b

Desorption of F+ induced by core-level excitation with synchrotron radiation has been investigated on the CaF2(111) film produced on Si(111). The ion yield is proportional to electron yield in the region of the Ca-2p edge, while an enhancement of the

A mechanism for three-photon double ionization of atoms by extreme-ultraviolet free-electron laser pulses is revealed, where in a sequential process the second ionization step, proceeding via resonant two-photon ionization of ions, is strongly enhanc

A gas monitor detector was calibrated to a cryogenic radiometer for measuring the radiant power of EUV‐FEL (extreme ultraviolet free electron laser) at the wavelengths of 51 nm and 61 nm. The output signals of the gas monitor detector showed good l

In this work we report observation of ultra-fast switching of vacuum ultra-violet (VUV) light caused by saturable absorption by a solid metal foil. A sub-picosecond VUV pulse from a free-electron laser located in SPring-8 is focused on a metal target

We determine electron delocalization rates in liquid water and ice using core-hole decay spectroscopy. The hydrogen-bonded network delocalizes the electrons in less than 500 as. Broken or weak hydrogen bonds--in the liquid or at the surface of ice--p
