  • During photoionization, the recoil of the atom or molecule due to the ejected electron can subtly alter the observed photoelectron and Auger spectra from expectations. Here, the authors study Auger emission from isolated neon atoms and see a Doppler shift in the spectrum resulting from translation recoil.

  • Resonant inelastic X-ray scattering measurements suggest that the oxidized oxygen species in high-energy Li-rich oxide cathodes are trapped molecular O2, which is also observed in O-redox-inactive materials. This suggests that resonant X-ray inelastic scattering measurements generate these species, and molecular O2 is not responsible for voltage hysteresis and decay.

  • Radiation damage in biology is largely mediated by radicals and low-energy electrons formed by water ionization and extensive, localized water ionization can be caused by ultrafast processes following the core-level ionization of hydrated metal ions. Now it has been shown that, for Al3+ ions, relaxation occurs via sequential solute–solvent electron transfer-mediated decay.
