Electron spectroscopic studies of temporary negative ion resonances which correlate with excited electronic states have been generahy limited to atomic or diatomic systems (for recent reviews see ref. [ 13). In this report we wish to indicate the existence of excited state negative ion resonances in methane which appear to be of the bound state or closed channel type. These results, extending the range of molecular complexity of systems exhibiting c!ased channel excited state resonances? are due probably tc stabilized Jahn-Teller distorted states expected for negative ions correlating with appropriate methwe excited states.
