The atomic emissions of heavy elements exhibit relatively small Doppler widths even at inductively coupled plasma (ICP) temperatures and they also possess complex electronic structure that often results in several electronic states with isotopic splitting. For these reasons, lead and uranium were selected for observing the feasibility of utilizing the ICP atomic emission spectrometry for isotopic analysis. The Pb II 537.2 nm line was selected and resolution of the emission from Pb 206, 207 and 208 isotopes were clear. For uranium the 424.4 nm line was chosen. Figures are presented showing the isotopic patterns of this line for a /sup 235/U-/sup 238/U mixture and a /sup 235/U-/sup 236/U-/sup 238/U mixture that were excited by the ICP. The /sup 235/U-/sup 238/U is excellent and the /sup 235/U-/sup 236/U splitting (0.01 nm) is very well resolved. (ATT)
