Title: H{sup −} formation by neutral resonant ionization of H(n=2) atoms

A mechanism for producing hydrogen anions in a low density, low energy hydrogen plasma is proposed. The observation in a plasma ion source that the anion output is quadratically related to the Lyman-α radiation suggests that anions could be formed in collisions between atoms in the first excited state. A potential energy plot for the hydrogen molecule is developed that includes a high energy ionic state, comprising a proton and the weakly bound H{sup −}(2p{sup 2} {sup 3}P{sup e}) ion, revealing a path to stable anion formation.
