In the experiments of secondary ion emission on metal and alloy surfaces, elements with higher electronegativity are enhanced to a greater extent by the presence of oxygen than those with lower electronegativity; the secondary ion yields for Cu, Zn, etc. in some alloys do not reach a saturation state; and there exists linear relation between the yield of positive metallic ions and that of negative oxygen ions with the change of oxygen pressure. These experimental results will be significant to improve quantitative SIMS analysis.
