Inner-shell near-threshold photoionization of A @ C60 endohedral atoms
Calculations were performed to provide insight into both differential and total photoionization cross sections of endohedral atoms with particular emphasis on confinement and molecular resonances in these cross-sections. Low-energy inner-shell photoelectron angular distribution spectra for at-the-center endohedral atoms were found to be identical in shape to those for free atoms, but as the photoelectron energy increases, the similarity disappears. In addition, for low-energy spectra, this similarity was explained physically and, thus, a justification for the use of empirically adjusted spherical model potentials to represent the role of the confinement in photoionization of endohedral atoms was presented.
