Abstract: The spectra of pulsed cathodoluminescence (PCL) of CsI:Tl, YAG:Ge$^{3+}$,Tb$^{3+}$, and LFS-3 crystals excited by high-power ($\sim$ 10 MW) short-time ($\sim$ 2 ns) action of an electron beam with an average particle energy of $\sim$ 150 keV have been compared to the spectra of steady-state luminescence of the same crystals under the action of $\gamma$-photons with an energy of 511 keV emitted from a radioactive $^{22}$Na sample. It is established that the two spectra are identical, which allows the PCL method to be used for rapid analysis of scintillation crystals.
