The spectra of the creation of long‐lived Frenkel defects (F, H and α, I pairs) by 7.5 to 9.0 eV photons and the thermal annealing of defects created at exciton decay or at the recombination of electrons with holes are measured in KCl crystals by the luminescence methods at 4.2 K. Pairs of defects with various distances between F and H centers are formed at the decay of Γ (1/2) and Γ (3/2) excitons with n = 1, 2. The generation efficiency of long‐lived α, I pairs is especially high at the tunneling recharge of F, H pairs created via the decay of Γ (3/2) excitons.
