Ways to spin resolved core-hole-clock measurements

Abstract

We describe two different ways to spin resolved measurements of charge delocalization times by resonant photoemission. The first approach is based on spin selective population of the core-to-bound resonance, and the second on spin resolved detection of the emitted decay electrons. Whereas the first method requires distinct electronic properties of the material under investigation, no such limitations exist for the second approach. In particular, it can be used for studies of organic materials containing the light elements of the second row of the periodic table.
