Abstract
Using the on-line mass separator ISOLDE (CERN) radioactive 111mCd atoms were produced and deposited on Mo (110) surfaces under standard UHV conditions. The deposition is performed in 3 steps. First the 60 kV 111mCd atoms are implanted into a Mo oven. This oven then is heated to 1200 K in order to deposit the activity on a Mo foil. This Mo foil is now transferred in front of the prepared specimen surface and heated to a temperature of 600 K. At that temperature the 111mCd activity is now deposited on the LN2 cooled specimen with little thermal loading of the single crystals. The estimated specimen temperature during this “onplantation procedure” is below 90 K. The concentration of 111mCd probe atoms on the Mo (110) surface does not exceed 3•1011cm-2, i.e. 10-4 monolayer.
