Bi-Pb-Sr-Ca-Cu-O superconductor is irradiated at liquid nitrogen temperature with 120 MeV 16O ions up to the fluence of 3.5×1014/cm2. Transition temperature Tc and critical current Ic at 77.3 K decrease with increasing ion fluence. Annealing of the specimen up to 300 K after irradiation causes a slight recovery of Tc and Ic. However, recovery of the electrical resistance above 100 K is not observed.
