PROPERTIES OF MERCURY-LIKE CENTRES IN ALKALI HALIDES
In terms of a model which suggests a strong interaction of the optical electrons of a mercury-like centre with nontotally symmetric vibrations of the crystal lattice, the expressions for the calculation of the parameters of the triplet excited state of mercury-like centers in alkali halides from the temperature dependence of the emission decay time are derived by using a one-foton approximation. By basing on the measured by us published by other authors the parameters of the tetragonal and trigonal minima of the adiabatic potential of the triplet excited state are calculated for all the mercury-like centres in KCl, KBr and KI crystals investigated up to now.
