Evaporation techniques for preparing rare-earth targets used in heavy-ion nuclear physics.

摘要

The preparation techniques for producing nuclear targets of the rare-earth isotopes depends greatly upon the physical properties of the particular rare-earth element. In most cases the isotope is supplied in the oxide form which then requires reduction to obtain the metal. Collection efficiencies will be discussed as this is of vital importance when considering the price and availability of the isotopic material. 12 refs, 2 figs., 4 tabs.
