Abstract
High-resolution metastable excitation function measurements have been made in the doubly excited states region for Ne, Ar and Kr targets. Comparison of the spectra obtained suggests that the gross features are due to negative-ion resonances. Previous techniques which have proved successful in the identification and classification of resonances in the rare gases at energies below the first ionisation threshold are applicable in this energy region also and assignments for a number of resonances are suggested. Where appropriate, comparisons are made with data obtained by other techniques. The modified Rydberg formula has been used to predict energies for both doubly and triply excited configurations.
