[en] Kinetics of scintillator luminescence under excitation by electron subnanosecond pulses is studied. Studied CsI, CsI-Tl, KI, KI-Tl, NaI-Tl monocrystals were irradiated by single pulses of high-current electron accelerator (energy of 450 keV, pulse length at half-height 50 ps, current density of a sample 100 A/cm²). Time resolution under experimental conditions is 10 ps. It is shown that in kinetics of increase of alkali-halogen scintillator luminescence in excitation by ∼ 50ps electron pulses recombination processes both with participation of free charge carriers and intermediate charge carrier trapping are manifested

[en] For CsI exposed to electron pulses of about 50 ps at 300 K an inertial growth of the F-centre absorption in the course of time (up to 200 ps) has been detected. The growth is associated with the zone-electron and V_k-centre-recombination kinetics. The cross section for the electron capture by the self-trapped hole has been evaluated

[en] Scintillation mechanism in NaI-Tl (Tl⁺ concentration -2x10¹⁸CM^-3) was studied. Activator luminescence (λ_max=420nm) was excited by 450 keV electron pulses. Luminescence kinetics of NaI-Tl in λ_max=420nm band at 300K was investigated. It is shown that at 300K about 60% of scintillation burst luminosity is conditioned by thermally activated processes, and 40% - by fast energy transfer with participation of nonrelaxed electrons and holes

[en] The short-lived absorption for α-Al₂O₃ at 80 K induced by electron pulses with the duration of 50 ps is measured in the spectra region of 1.3-3.0 eV. An absorption band with the maximum at 2.0 eV and the decay time of 1.8-5/0 ns in different samples has been detected. Kinetics and spectrum of the absorption band have been interpreted in terms of free holes' intrabend light absorption
