Time-resolved Ax-luminescence of NaI:Tl under electron pulse irradiation
This paper studies spectral-kinetic properties of NaI:Tl cathodoluminescence registered in the region of Ax-band with maximum 425 nm within the time interval of 10⁻⁸-10⁻² s. Ax-luminescence of NaI:Tl crystal has been excited with an electron pulse (Ee = 0.25 MeV, t1/2 = 10 ns, W = 0.003...0.16 J/cm2...
