摘要：

Optical absorption and photoluminescence spectra have been measured in LIF crystals colored for the first time with 5 MeV electrons. The measurements show that this kind of irradiation reduces (much more than gamma-rays) the production of complex aggregate defects with respect to that of F-3(+) and F-2 centers. Moreover, the laser active F-3(+) centers can be preferentially created in place of F-2 centers by decreasing the irradiation temperature. (C) 1998 Elsevier Science B.V. All rights reserved.
