An experimental investigation was made of the superconducting transition in the intermetallic compound Nb/sub 3/Ge irradiated in the superconducting state in a cryochannel of a nuclear reactor. The critical temperature T/sub c/ of the superconducting transition in a thin (2 ..mu..) film of this intermetallic compound, deposited on a molybdenum wire 0.5 mm in diameter, was determined by an intrareactor resistance method. It was found that T/sub c/ of the Nb/sub 3/Ge--Mo composite was only slightly affected right up to the fast-neutron fluence 2.3 x 10/sup 18/ cm/sup -2/ (E>1 MeV) at the irradiation temperature of 12 K: the transition temperature decreased from 19.5 K to 18.8 K. It was established that a significant degradation of T/sub c/ occurred during the subsequent prologed annealing at 300 K and this was accompanied by an increase in the width of the superconducting transition, indicating that inhomogeneities in the form of disordered or nonstoichiometric clusters appeared in the matrix.
