Investigating mechanisms of state localization in highly ionized dense plasmas
Producción CientÃficaWe present experimental observations of Kβ emission from highly charged Mg ions at solid density, driven by intense x rays from a free electron laser. The presence of Kβ emission indicates the n=3 atomic shell is relocalized for high charge states, providing an upper constraint on the depression of the ionization potential. We explore the process of state relocalization in dense plasmas from first principles using finite-temperature density functional theory alongside a wave-function localization metric, and find excellent agreement with experimental results.This work has been supported by the Spanish Ministry of Science and Innovation under Research Grant No. PID2019-108764RB-I0
Investigating Mechanisms of State Localization in Highly-Ionized Dense Plasmas
We present the first experimental observation of K emission from
highly charged Mg ions at solid density, driven by intense x-rays from a free
electron laser. The presence of K emission indicates the atomic
shell is relocalized for high charge states, providing an upper constraint on
the depression of the ionization potential. We explore the process of state
relocalization in dense plasmas from first principles using finite-temperature
density functional theory alongside a wavefunction localization metric, and
find excellent agreement with experimental results.Comment: 22 pages, 13 figure
