    Abstract

    The conditions for the formation of alternative polarity recombination centers of point defects are discussed and their structure is investigated. The centers are shown to be stable point defect-impurity complexes that reverse the polarity while trapping free point defects. Having low mobility and a large trapping radius, these complexes may be efficient point-defect recombination centers. The experimental data are presented on the effect of rare earth elements on the recovery of the electrical resistivity and swelling of low alloyed nickel to support the existence of the recombination centers.
