    Radiationless electronic relaxation of the F center in NaI

    No full text
    The temperature dependence of the ground-state recovery of the F-center in NaI after optical excitations is studied with a pump-probe laser technique. At 10 K the lifetime of the relaxed excited state (tens of ns) is identified together with a much smaller 10 ps contribution possibly related to the Dexter-Klick-Russell cross-over process. © 1994
