Abstract
The conductivity of KCl, KBr, NaCl, CsI crystals excited by electron p ulses (50 ps, 0.2 MeV) has been investigated. The current pulse for KC l, KBr and NaCl reproduces the form of the exciting impulse within the resolution ability of the recording system. The decay of the current pulse for CsI is about 1 ns and is described by the second-order kinet ics. The coincidence of the current pulse decay time for CsI with the time of F-center creation enables us to identify this duration as the lifetime of the band electrons. In this case for the band electron mob ility one can obtain mu = (8 +/- 2) cm(2)/Vs.
