The H/sup -/ formation process has been investigated in a magnetically filtered multicusp source operated at a modest plasma density. By use of a mixture of xenon and hydrogen gas, it is found that the production of H/sup -/ ions in the tandem discharge geometry is consistent with a model of dissociative attachment of low-energy electrons to vibrationally excited hydrogen molecules.
