FORMATION OF H(-) BY ELECTRON IMPACT ON H2 AT LOW ENERGY

Abstract

The document reports the formation of the atomic hydrogen negative ion by electron impact on H2 very close to the theoretical threshold for the production of H(-) and H with zero kinetic energy via the process e + H2 yields H(-) + H. H(-) formation was found with a very sharp onset at an electron energy of 3.73 = 0.07 eV and a very steeply rising, albeit small, cross section which peaks very close to its onset. This observation leads to a better understanding of the potential-energy curves of the H2(-) system and has a bearing on the interpretation of vibrational excitation in H2.
