Where are the electric fields that would cause electromigration? There are no fields in copper pipes as far as I know. Kullander does say ". . . it’s remarkable that nickel-58 and hydrogen can form copper-63 (70%) and copper-65 (30%)." I guess that means they measured the isotopes. They used XRFS and ICP-MS. XRFS measures only elements as I recall, whereas ICP-MS detects isotopes. It would be a little odd if the reaction produced copper with a natural isotopic distribution. - Jed
