Formation of regular distribution of point defects on their stochastic generation correlated with randomly arranged nonuniformity of irradiated metal

With accounting for mutual correlation a study is made into the combined influence of fluctuations of radiation-induced defect generation rate and nonhomogeneities of irradiated metal on the criterion of interacting defect periodical distribution. The criterion is found for the transition of a stationary uniform random field of radiation defect density to a random field which mean value and dispersion periodically vary with space. Fluctuation corrections as for a critical value of displacement d=generation mean rate so for a period of forming structure are determined for a number of limiting cases
