A Pratical Approach to the Self-Shielding Problem in Low-Flux Neutron Activation Analysis.

Abstract

It has been suggested (9) that the results from a direct determination of oxygen in meteorites may be used to check the oxidation state of the iron in the oxidized form in these materials. The present method with the estimated errors for oxygen (Table IV) could be used for this_purpose only for samples containing more than 60% of oxidized iron. Meteorites (and rocks) have
