摘要：

A decrease in the critical current density J(c) of a YBa2Cu3O7-x thin film is observed after its irradiation by 4-MeV electrons. It is shown that the temperature dependence of J(c) agrees with the idea of a granular structure of the film, with intergranular contacts of the superconductor-metal-insulator-superconductor type.
