His calculations were published in Physics Letters (chosen by Pippard because it was a new journal) in a paper entitled "Possible new effects in superconductive tunnelling," received on 8 June 1962 and published on 1 July. They were confirmed experimentally by Philip Anderson and John Rowell of Bell Labs in Princeton; this appeared in their paper, "Probable Observation of the Josephson Superconducting Tunneling Effect," submitted to Physical Review Letters in January 1963.
