Electron-emission processes following 5pphotoexcitation in fcc Yb

The electron-emission decay channel for photoexcited fcc Yb 5p3/2 and 5p1/2 core levels is observed by measuring the photoionization cross-section curves σ*, for the 4f subshell and valence-band electron states in the photon energy range 23--50 eV. ONN Coster-Kronig, 5p-5d resonant photoemission, and 5p-5d giant dipole autoionization decay channels produce well-resolved structures in the photoemission and σ* curves. These processes shed light on the electronic structure of fcc Yb, which is largely hidden in conventional photoemission experiments.
