摘要:
AbstractFrom an extensive series of measurements of ϕ(ρz) curves, at electron energies between 6 and 15 KeV, an empirical formula;ϕ(R)=DKn(KR)n−1exp(−(KR)n) where R=ρz+ρzo, was developed to accurately describe the shape and magnitude of the measured curves. On the basis of this equation a quantitative correction for absorprion and atomic mumber effects has been derived for low electron energies. A comparision of quantitative analysis using the above equation wit other absorption and atomic number corrections shows better agreement between calculated and known concenequation to a correction for fluorescence due to characteristic lines is
