摘要
The exoelectron-emission from LiF-crystal surfaces after cleavage and excitation by electrons or X-rays is investigated in high vacuum and ultrahigh vacuum. As we show by measurements in ultrahigh vacuum, in contrast with metals the exoelectron-emission of LiF-crystals in high vacuum is not essentially influenced by surface layers. Traps of the LiF-crystal are responsible for the emission. We can distinguish between surface states and volume traps -M- and F-colour centres - responsible for the exoelectron-emission from LiF-crystals. © 1969 Springer-Verlag.
