Tthe method of absorption spectroscopy with nanosecond resolution is used to study transient absorption in nominally pure crystals of CaF 2 irradiated by a pulse of fast electrons. Optical absorption caused by self-trapped excitons appears in the form of a superposition of bands with half-widths of no more than 0.2 eV in both the electron and hole components. These groups of bands are assigned to absorption of F, H pairs in various configurations. We observe a regular change in the spectral-kinetic characteristics depending on the distance between the components of the pair.
