The primary effort of this contract has been directed largely to an increased understanding of cooperative phenomena observed to occur between impurity dopant ions in ionic crystals. The phenomena observed were a ion pair absorption in LaCl3 by Ho3 Nd3, by Ho3 Pr3, and by Pr3 Nd3, in which case one photon is absorbed by two ions b satellite structure in which case the perturbation caused by the mutual interaction of neighboring ions produces a shift and splitting of the energy levels relative to the single Ho3 ion levels c multiple ion relaxation processes in Ho3 doped LaCl3, in which case the excitation energy of a single ion is shared nonradiatively with one or more ions in the decay process.
