Abstract

Abstract The effects related to the He gas incorporation into the YBa 2Cu 3O 7−y lattice are re-examined. Contrary to previously reported data, we could not observe any He-gas effect on T c. We conclude that if He is incorporated it must be absorbed in the intergranular empty spaces in polycrystalline samples.
