摘要：
The decay curves for Auger-free luminescence from BaF2 and CsCl crystals excited by VUV photons and high-energy electrons from 511 keV annihilation radiation from a Na-22 beta+ source have been measured. The existence of a faster luminescence component under VUV photon excitation suggests some unknown relaxation process for the outermost-core holes which are produced in the order of 10(-6) cm from the crystal surface.
