TWO ZONES OF "IMPURITIES" OBSERVED AFTER PROLONGED ELECTROLYSIS OF DEUTERIUM ON PALLADIUM

In experiments carried out recently in which hydrogen was electrolyzed from water in contact with a palladium electrode, the concentration and depth of impurities were measured as a function of electrolysis time. It was found that after 3 weeks, two different sets of impurities could be observed, one set within 50Å of the surface and another set different chemical spaces, about 1μ inside the metal.
