摘要：

A possible energy instability of some color center systems is pointed out, including an anion vacancy (α-center) in alkali halide crystals. When an optical electron passes from an F-aggregate center to an α-center, the system as a whole occupies a lower lying energy level. As an example the probability of the spontaneous radiative tunnel transition M + α → M+ + F in a KC1 crystal is calculated. © 1979.
