| Abstract: | The influence of ∼1-MeV γ irradiation on polycrystalline and monocrystalline copper is investigated by recording acoustic
radiation and by x-ray structural analysis. It is concluded that γ quanta of that energy indirectly influence the properties
of the material by short-lived excitation of the subsystem of external electrons involved in interatomic bonds, without markedly
increasing the concentration of point defects; this excitation is localized in defective regions of the crystal lattice and
determines the restructuring of these local regions.
