Phys. Rev. Lett. 42, 1769–1773 (1979)Superconductivity in Irradiated PalladiumReceived 19 March 1979; published in the issue dated 25 June 1979 Pure palladium films, evaporated between 4.2 and 300 K, can be transformed into superconductors by means of irradiation at low temperatures with He+ ions. The maximum transition temperature obtained is 3.2 K. It is shown that the presence of a special kind of defects produced during the irradiation is a necessary precondition for the occurrence of superconductivity. © 1979 The American Physical Society URL:
