当超过芯能级的吸收阈值时，除了直接光致发射通道外，第二个间接通道打开时，就会发生共振光致发射现象。可能会出现排放截面的大幅增加，但这一过程的性质仍然不明朗。在光电子能谱实验和理论计算中使用新的磁线性二色性，我们现在可以清楚地证明，过程的时间匹配和能量匹配是真正的{Open_Quotes}共振光电发射的必要条件。
The phenomenon of resonant photoemission happens when, in addition to a direct photoemission channel, a second indirect channel opens up as the absorption threshold of a core level is crossed. A massive increase in emission cross section can occur, but the nature of the process remains clouded. Using novel magnetic linear dichroism in photoelectron spectroscopy experiments and theoretical calculations, we can now clearly demonstrate that temporal matching of the processes as well as energy matching is a requirement for true {open_quotes}resonant photoemission.{close_quotes} {copyright} {ital 1998} {ital The American Physical Society}
