摘要
A simple and effective instrumental neutron activation analysis for iron meteorites is presented in this study. In order to design the analytical procedure, self-absorption of gamma-rays on samples, interfering nuclides and their respective reactions were examined. Seventeen elements (Fe, Co, Ni, Cu, Ga, Ge, As, Mo, Ru, Rh, Sb, W, Re, Os, Ir, Pt and Au) could be nondestructively determined in Canyon Diablo and Cape York iron meteorites. Our data of these two iron meteorites are consistent with the corresponding literature values. This study confirms that our analytical procedure with INAA is simple and effective in classification of iron meteorites.
