- We derive core-level spectra for doped free-standing bilayer graphene. Numerical results are presented for all nine combinations of the doping concentrations 1012 cm-2; 1013 cm-2, and 1014 cm-2 in the two graphene sheets and we compare the results to the reference spectra for monolayer graphene. We furthermore discuss the spectrum of single-particle inter-band and intra-band excitations in the ωq-plane, and show how the dispersion curves of the collective modes are modified in the bilayer system.
