47K atoms produced and separated at ISOLDE were embedded in a platinum
foil by implantation, decaying therein to 47Ca. The foil was transfer
red to a vacuum chamber, and a sizeable fraction (around 10%) of the 4
7Ca was extracted from it by ohmic heating. The extraction procedure w
as repeated successfully for a number of times over a long period. An
equivalent procedure failed to extract the 47Ca atoms out of a tungste
n foil.
