摘要：

Relative photoelectric yield spectra of thin films in KCI, KBr and RbCl are investigated in the photon energy 7 eV-40 eV range at 80 K as well as at room temperature. Several new characteristics of the spectra due to the thin film specimens and due to the lower temperature are observed. It is revealed that the yield spectra dominantly reflect the photo-absorptions modified by the inelastic electron-electron scattering in the valence excitation region and by the Auger process especially in the core excitation region. A large yield peak due to the next deeper core level K(+)3s or Rb(+)4s is newly identified in a photon energy range of 30-40 eV. Interband thresholds of the yield spectra are observed and the electron affinities are derived.
