LANTHANUM
Natural Abundance, Stable Isobars aLa138, 0.089%, Ba138 La139, 99.911%, Ce138 The only compound which has been used in the separation of lanthanum isotopes is anhydrous lanthanum trichloride. The average charge consists of 150 g LaCl3 in a style C-16 graphite charge bottle. The method of charge preparation and the recycle and recovery procedures developed for samarium are used for all rare earth elements with the exception of cerium. The rare earth techniques are described in detail only for samarium and cerium. aLa138 is radioactive with a half-life of 1.1 x 1011 years. |
