Ultrafast Nuclear Dynamics in Double-Core Ionized Water Molecules
arxiv(2024)
摘要
Double-core-hole (DCH) states in isolated water and heavy water molecules,
resulting from the sequential absorption of two x-ray photons, have been
investigated. A comparison of the subsequent Auger emission spectra from the
two isotopes provides direct evidence of ultrafast nuclear motion during the
1.5 fs lifetime of these DCH states. Our numerical results align well with the
experimental data, providing for various DCH states an in-depth study of the
dynamics responsible of the observed isotope effect.
