Divalent ions in alkali halides. II. NaCl:Mn2+evaluation of vacancy jump kinetics

For pt. I see abstr. a72486 of 1970. Recent evaluations of the frequencies of the dielectric relaxation modes in NaCl doped with Mn 2+ and of the rates of two of the four types of jump available to a vacancy attached to a divalent ion, together with an experimental assessment of dipole population, are used as the basis of a reappraisal of an earlier experiment on anelastic relaxation by Dreyfus and Laibowitz (1964). It is shown that for the NaCl:Mn 2+ system a new decomposition of the anelastic loss peaks is required which includes all of the relaxation modes. The kinetics of the vacancy jump rates W i can be expressed in the Arrhenius form W i =P i exp(-h i /kT).
