| Abstract: | Copper mill materials from Utah and Nevada and rock cores from a geothermal drill hole at the Valies Grande Caldera in New Mexico were irradiated at the Los Alamos Scientific Laboratory with neutrons from a californium-252 source (about 1010 n s-1), and the capture γ-rays were measured. The copper response, based on the 6.89-MeV double escape line, agreed sufficiently well with the known chemical composition of the materials to indicate usefulness of this technique for exploring copper deposits and for monitoring metallurgical extraction processes. |
