Abstract
Radiation-induced changes in the superconducting transition temperatur e T(c) and the zero-field critical current density at 4.2 K are report ed for Ba0.6K0.4BiO3 (BKBO) thin films irradiated with 1, 2, and 3 MeV protons and 4 and 6 MeV helium ions. Displacement damage decreases T( c) at the same rate for BKBO as for the high-T(c) cuprates. The critic al current density decreases approximately exponentially with increasi ng fluence at a rate that is directly proportional to the nonionizing energy loss of an incident particle.
