Abstract
The photoelectric yield of thin films of solid Ar, Kr, and Xe has been studied in the exciton and interband range between 10 and 32 eV using synchrotron radiation. Decay of excitons contributes only weakly to photoemission. Electron affinities are estimated from the thresholds for strong emission. High absolute yields above the band gap combined with only faint spectral fine structure and a broad minimum at more than twice the gap energy are related to electron-electron scattering.
