论文摘要
我们可以测量多快的过程？ ATTOSEND物理学解决了科学中可测量时间的限制。原子X射线激发态提供了一种以化学特异性研究极快动态的方法。在黑色磷中，X射线激发电子可以在22.7个attoseconds中重新定位。将P 1S核心孔的寿命作为时间基量，无辐射衰变光谱可用于在时间尺度上研究电荷转移过程（24个attoseconds）。我们证明，该技术可以扩展到核心孔寿命的几％，这比以前想象的要小。
How fast processes can we measure? Attosecond physics address the limit of measurable time in science. Atomic X-ray excited states offers a way to study extremely fast dynamics with chemical specificity. In black phosphorous an X-ray excited electron can relocate in 22.7 attoseconds. Using the lifetime of the P 1s core-hole as time-base, the radiationless decay spectrum can be used to study charge transfer processes on the time-scale of the atomic unit of time (24 attoseconds). We demonstrate that the technique can be extended to within a few percent of the core hole's lifetime, an order of magnitude smaller than previously thought.
