Fig. 1: Scheme of multiband final states (MBFSs).
From: High-energy photoemission final states beyond the free-electron approximation
(a, top) Multiple (here a pair of) final-state Bloch waves and (bottom) the initial-state one; b The corresponding out-of-plane band structure features multiple final-state bands, which yield multiple ARPES peaks from one initial band. The shading shows Δkz of the final-state bands.
