Non-cosmogenic lithium-6 in iron meteorites

Description

A neutron activation method is used to measure 6Li via the reaction 6Li(n,α)3H in iron meteorites. It is found that most 6Li 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 ppm 6Li, while in the bulk sample 6Li ranges from 0.02 to 10 ppb. Average 6Li contents (ppb) for various classes are IA, 1.8; IIAB, 1.6; and IIIA, 0.4. Cosmic-ray-produced 6Li is generally much smaller than the native 6Li. (orig.)
