| Abstract: | A neutron activation method is used to measure6Li via the reaction6Li(n, α)3H in iron meteorites. It is found that most6Li occurs in non-metallic inclusions which can be separated by dissolution of the metal in 4 M H2SO4. The non-magnetic portion of such a residue has as high as 0.9 ppm6Li, while in the bulk sample6Li ranges from 0.02 to 10 ppb. Average6Li contents (ppb) for various classes are IA, 1.8; IIAB, 1.6; and IIIA, 0.4. Cosmic-ray-produced6Li is generally much smaller than the native6Li. |
