1. A process for producing negatively charged ions of hydrogen which comrises:

  • a. cooling hydrogen gas to below 300°

    K.;

    b. vibrationally exciting the molecules of the said hydrogen gas to a first vibrational energy state higher than the ground vibrational state;

    c. anharmonically pumping said gas to a second vibrationally excited state higher than said first state; and

    d. impacting the cooled and vibrationally excited hydrogen gas molecules with energetic electrons to produce, by dissociative attachment, neutral hydrogen atoms and negatively charged hydrogen ions.
