Abstract: | We make a theoretical study of the shake-up of the 1s photoemission of C60. The method takes into account the N-body reactions of the π and σ electrons which appear
during the formation of the photoemission hole on one carbon atom. We analyze the origin of the satellite in the spectra due
to transitions between N-body states. Our calculation shows that the
satellite spectra is essentially given by N-body transitions which involve the creation of one or two electron-hole pairs.
The method has been applied also to C48N12. The situation is more
complex. The spectra of the two most stable species have been investigated. Moreover the influence on the spectra of the position
of the hole created on the carbon atom in C48N12
has been examined (all the carbon positions are not equivalent for some isomers). |
