Stability of electrons—monomers and dimers—in gamma-irradiated hydroxide glasses

The increase of temperature from 77 K brings about the retrapping of electrons and/or recombination processes manifested by the changes of absorption spectra and ESR signals. The new absorption bands at 700–840 nm, which belong to diamagnetic electron dimers, have been observed at 215–225 K. These species are connected with NaOH·X H₂O hydrates as it has been shown by near-IR spectra. The dispersive kinetic parameters of photobleaching of electrons—monomers and dimers—at 80 K have been measured.
