AI总结:

本文首次实验观测到固体密度高电荷态Mg离子的K$_β$发射,证明高电荷态下n=3壳层重新局域化,并结合有限温度密度泛函理论与波函数局域化度量从第一性原理验证了实验结果。

摘要:

我们首次在实验上观测到由自由电子激光强X射线驱动的固体密度高电荷态Mg离子的K$_β$发射。K$_β$发射的存在表明在高电荷态下$n=3$原子壳层重新局域化,从而为电离势下降提供了上限约束。我们从第一性原理出发,利用有限温度密度泛函理论以及波函数局域化度量探索了致密等离子体中的态重新局域化过程,发现与实验结果具有极好的一致性。

英文摘要:

We present the first experimental observation of K$_β$ emission from highly charged Mg ions at solid density, driven by intense x-rays from a free electron laser. The presence of K$_β$ 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 wavefunction localization metric, and find excellent agreement with experimental results.
