Addendum to Ab initio treatment of final-state spin-orbit interactions: Photoionization of the 6s electron in cesium

A previous calculation of the cesium 6s→εp photoionization cross section is extended to include interchannel coupling to the 5p→εd photoionization channels. For photon energies in the range 0.35 a.u.≲ℏω≲1.12 a.u., i.e., just above the near-threshold cross-section minimum, the 6s photoionization cross section is found to be dominated by 5p→5d resonance transitions. No experimental data exist for this energy region
