“…This finding was based on experiments with thin films of NaCl deposited on transmission electron microscopy (TEM) grids and electrons irradiated in an electron microscope at 5Ð40 keV range (Medlin and Howitt, 1994). A low G value of ~ 2 to 5 pairs/100 eV for initial production of F-H pairs in alkali halides at room temperature was reported (Hobbs 1979, Medlin and Howitt 1994, Sonder and Sibley 1971. However, because most of these rapidly recombine, researchers suggest that the G value near room temperature for stable F-H production in NaCl is ~0.032 pairs/100 eV (Hobbs 1979, Medlin and Howitt 1994, Itoh and Tanimura 1990).…”

The phenomenally large enhancement in conductivity observed when Li-doped MgO crystals are oxidized at elevated temperatures was investigated by dc and ac electrical measurements in the temperature interval 250-673 K. The concentration of [Li] 0 centers (Li + ions each with a trapped hole) resulting from oxidation was monitored by optical absorption measurements.At low electric fields, dc measurements reveal blocking contacts. At high fields, the I − V characteristic is similar to that of a diode connected in series with the bulk resistance of the sample.

“…The three curves have a similar shape, corrresponding to the well-known [5] two stages of irradiation, an early fast stage, and a late slow stage. It will also be noted that the number of dipoles destroyed by irradiation is very much greater than the number of trapped electrons or holes.…”

The concentration of impurity-vacancy dipoles in potassium bromide crystals doped with strontium bromide was measured using the ionic thermocurrent (ITC) technique.The parameters of the dipole relaxation are: fundamental relaxation time 4 x 10-14 8, activation enthalpy 0.66 eV. The effect of 6oCo y-irradiation a t room temperature was to reduce the number of dipoles and t o increase the number of trapped holes and electrons, but t,he number of trapped holes and electrons, measured by optical absorption, was about 30 times smaller than the number of dipoles destroyed. It is proposed that the effect of irradiation is t o increase the rate of aggregation of dipoles, primarily into trimer aggregates, through temporary electron trapping by strontium ions.Mit dcr Ionen-Thermostrom(1TC)-Methode wurde die Konzentration der StorstellenLeerstellendipole in Kaliumbromidkristallen, die mit Strontiumbromid dotiert waren, bestimmt. Die Parameter der Dipolrelaxation sind : Grundrelaxationszeit 4 x 10-14 s, Aktivierungsenthalpie 0,66 eV. Der EinfluD von 6oCo-y-Bestrahlung bei Zimmertemperatur rednziert die Zahl der Dipole und erhoht die Zahl der angehafteten Locher und Elektronen, jedoch war die Zahl der angehafteten Locher und Elelrtronen, die durch optische Absorption gernessen wurde, etwa 30mal geringer sls die Zahl der zerstorten Dipole. Es wird sngenommen, daB der EinfluB der Bestrahlung in der Erhohung der Geschwindigkeit der Aggregation der Dipole, hauptsachlich zu Trimer-Aggregaten, durch zeitweiliges Elektronenanhaften a n Strontiumionen besteht.
