This reveals information on both occupied and unoccupied states involved in the decay process, and correlation between the two. Although resonant photoemission in metals and their compounds have been studied quite extensively, few studies have been done for organic polymers. In this paper, resonant photoemission in poly (α-methylstyrene) is described, as an example of the results for organic polymers, as well as reviewing earlier works. The results showed that the resonant enhancement is clearly observed for the decay following the excitation to the lowest π^* band. Especially, the photoemission from the highest occupied band is largely enhanced. In addition, the energy shift of a valence peak was observed, suggesting the very fast relaxation within the lowest π^* band, which is peculiar to solids.

抄録

Resonant photoemission is a valence band photoemission process following the excitation of inner shell electron to a particular unoccupied state. This reveals information on both occupied and unoccupied states involved in the decay process, and correlation between the two. Although resonant photoemission in metals and their compounds have been studied quite extensively, few studies have been done for organic polymers. In this paper, resonant photoemission in poly (α-methylstyrene) is described, as an example of the results for organic polymers, as well as reviewing earlier works. The results showed that the resonant enhancement is clearly observed for the decay following the excitation to the lowest π^* band. Especially, the photoemission from the highest occupied band is largely enhanced. In addition, the energy shift of a valence peak was observed, suggesting the very fast relaxation within the lowest π^* band, which is peculiar to solids.
