title: Hydrogen atomic pair-ion production on catalyst surface.
abstract: To generate a hydrogen pair-ion plasma consisting of only hydrogen atomic pair ions, i.e., H(+) and H(-) ions, the efficient production of pair ions is required. When discharged hydrogen plasma is irradiated to a Ni catalyst, pair ions are produced on the catalyst surface. It is clarified that hydrogen chemisorption on the catalyst affects pair-ion production.
