Gold-doped germanium crystals were irradiated with 10 MeV electrons at T/sub irr/ = 360--380 K. An analysis was made of possible quasichemical reactions representing the interaction between vacancies V and host interstitial atoms Ge/sub i/ with gold atoms Au/sub s/ at the regular lattice sites. A calculation of the kinetics of accumulation of complexes was carried out for different relationships between the constants of the interaction of elementary defects with impurities. The experimental results together with the calculations demonstrated that irradiation of Ge:Au could result in the accumulation of impurity--vacancy (Au/sub s/V), impurity--divacancy (Au/sub s/ VV), and impurity--interstitial atom (Au/sub s/Ge/sub i/) complexes. The interaction of the Au/sub s/ VV complexes with the interstitial germanium atoms resulted in annihilation of the V--Ge/sub i/ pairs.
