Recombination And Dissociative Recombination Of H 2 + And H 3 + Ions On Surfaces With Application To Hydrogen Negative Ion Sources

John R. Hiskes, A. M. Karo

Abstract

A four-step model for recombination and dissociative recombination of H2+ and H3+ ions on metal surfaces is discussed. Vibrationally excited molecules, H2(v''), from H3+ recombination are produced in a broad spectrum that enhances the excited level distribution. The application of this latter process to hydrogen negative ion discharges is discussed.
