摘要： 在随后发生碎片化的电子衰变过程中，可以测量动能释放和电子能谱。 经典情况下，它们互为镜像，这一事实经常在实践中被使用。 推导了两种能谱的量子表达式并进行了分析。 结果表明，这些能谱携带互补的量子信息，并与不同参与电子态中的核动力学相关。 示例说明经典镜像图像可能失效，并揭示了背后的物理机制。 显示英文摘要

摘要： In an electronic decay process followed by fragmentation the kinetic energy release and electron spectra can be measured. Classically they are the mirror image of each other, a fact which is often used in practice. Quantum expressions are derived for both spectra and analyzed. It is demonstrated that these spectra carry complementary quantum information and are related to the nuclear dynamics in different participating electronic states. Illustrative examples show that the classical picture of mirror image can break down and shed light on the underlying physics.
