Abstract

We report evidence for the electron-impact excitation of doubly excited states in helium and H2 which are stable against autoionization. By detecting only long-lived (metastable) excited neutral states created by near-threshold electron scattering our technique discriminates against directly excited metastable states and is highly sensitive.
