Core electrons excitation energy

In inverse photoemission (and in case of high electron excitation energy) a final core state containing an additional electron (instead of a hole) may be created (for f-states fN -> f " ). Thus, and in the same hnes as for photoemission, a multiphcity of non... 

The baseplate is about 5 nm thick and contains a particular BChl a-protein complex, namely B795 (see Fig. 4 below). Here B stand for the word bulk, as in Chapter 3 where reference is made to lightharvesting BChl-proteins, and the number refers to the wavelength of the major absorption bands of the complex in the far-red. The B795-complex serves as an intermediate for transfer of electronic excitation energy from the chlorosome to components in the cytoplasmic membrane. The core complex in the cytoplasmic membrane consists of small core antenna complexes, B806-866, and the reaction-center complex (P865 in Chloroflexaceae sp.).

It is clear that the chemical reactions induced by core electron excitation are atom-specific. They generally depend upon the atomic site of the core hole and the electronic configuration of the core hole excited state. In this sense, the chemistry is selective. The chemistry can be selected by tuning the photon energy to produce particular core hole excited states. In another...
