Theoretical study of the valence and core photoemission spectra of C-60

The photoionization cross section and angular distribution relative to all primary ionizations in have been C-60 computed employing a convergent one-c entre expansion and an LDA hamiltonian over an extended energy range. The r esults show the presence of very sharp shape resonances both in the valence and core spectra. Good agreement is obtained with available experimental d ata, notably the HOMO/HOMO-1 oscillations, the absolute total photoabsorpti on and the available photoionization spectra, suggesting that more structur e should be observable in the low energy region.
