Abstract

A series of resonances with spacing 0.3 eV has been observed in the 11.2- to 12.5-eV range of the cross section for production of $H^{-}$ by dissociative attachment of electrons in $H_{2}$ . Comparison is made with resonances in the elastic scattering and vibronic excitation. Mechanisms involving vibrational levels of quasibound, excited states of $H_{2}^{-}$ are discussed.
