The conductivity of KCl, KBr, NaCl, CsI crystals excited by electron pulses (50 ps, 0.2 MeV) has been investigated. The current pulse for KCl, 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 kinetics. 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 mobility one can obtain m (8 AE 2) cm 2 /Vs. sssledovn provodimost5 kristllov KClD KBrD NaClD CsI pri vozuwdenii impul5smi Clektronov @50 psD HDP MeVAF predelh rzrexÏ §ej sposonoti sistemy registrii impul5s tok v KClD KBr i NaCl povtor¾et formu vozuwdÏ §ego impul5sF pd tokoE vogo impul5s v Csl sostvl¾et %I ns i opisyvets¾ kinetikoj vtorogo por¾dkF ovpdeE nie dlitel5nosti spd tokovogo impul5s v CsI s vremenem sozdni¾ FEentrov pozE vol¾et sozdt5 nlÏdemoe ztuhnie tokovogo impul5s s vremenem wizni zonnyh ClektronovD i poluqit5 dl¾ podviwnosti Clektronov znqenie m @8 AE 2A cm 2 aVsF

The paper presents the spectral and kinetic characteristics of the glow of coals from the Kuznetsk basin: brown, long-flame gaseous, gaseous and coke when excited by a pulsed electron beam (240 keV, 25 ns, 20 J/cm2). The glow that occurs in coals as a result of exposure at a temperature of T = 300 K has a luminescent character. The glow intensity increases in 50–100 ns with a subsequent decrease in ≈500 ns. The luminescence spectra of coals are presented at the moment of reaching the maximum luminescence intensity. Against the background of broadband luminescence, a number of narrow bands associated with the luminescence of polycyclic aromatic hydrocarbons are observed in all coals.
