Abstract

The spectral and kinetic parameters of electron-pulse-initiated transient absorption of oxygen-doped Ca,F₂ crystals were studied using pulsed spectrometry with a nanosecond time resolution. It is shown that the formation of a M_A ^- color centers in CaF₂-0.01M%CaO crystals occurs by thermally activated diffusion of the vacancies. Activation energy of M_A ⁺ color centers formation process of 0.4 eV is established.
