Abstract
The photoelectron spectra of the well-known fast scintillator material BaF2 have been recorded and compared with luminescence spectra measured earlier. A comparison of cross luminescence and photoelectron spectra for BaF2 has allowed to estimate the relaxation energy of the core (Ba 5p3/2) hole during its radiative lifetime with respect to cross-luminescence transition being equal to ~1.3Â eV. The photoelectron spectra obtained at low temperature favors the model of the F 2p-Ba 5p1/2 electron transition for the recently found emission band of BaF2 at 7.6Â eV.
