47K atoms produced and separated at ISOLDE were embedded in a platinum foil by implantation, decaying therein to 47Ca. The foil was transferred to a vacuum chamber, and a sizeable fraction (around 10%) of the 47Ca was extracted from it by ohmic heating. The extraction procedure was repeated successfully for a number of times over a long period. An equivalent procedure failed to extract the 47Ca atoms out of a tungsten foil.
