Abstract

Two-dimensional (2D) electrons on the liquid (4)He surface are mixed with atomic hydrogen. The density of 2D electrons decays as a result of the reaction with hydrogen atoms. The measured reaction rates indicates that two H atoms participate in the reaction to form a negative hydrogen ion, namely, H + H + e(-) --> H(-) + H. Then, H(-) submerges into the liquid. A direct three-body process and dissociative attachment of electrons to excited H(2)(14,4) molecules, which are produced by the surface recombination of hydrogen atoms, are discussed as a possible reaction mechanism.
