A method is given for the prediction of the position of the unknown spin level in the second excited state doublet commonly encountered in medium weight even-even nuclei. Data on all such nuclei known to have this doublet were plotted on an energy ratio graph of E/sub 1/(4)/E/sub 2/(2) vs. E/sub 2/(2)/E/ sub 1/(2), where E/sub 2/(2) is the energy of the 2+ level in the second excited state with respect to the first excited state, etc., and found to fit closely a smooth curve. This graph could be used in finding the second level of the doublet in such cases where the first level and the lower excited state are known. Also included on the graph is the curve expected from the asymmetric rotor theory (Davydov and Filippov, et al.; it is similar in shape to the experimental curve, but is displaced upward, in contrast with data for heavy nuclei, which fits the theoretical curve quite well.
