Abstract
Atomic Al develops a population inversion and stimulated emission in t he resonance fines when a solid target in a H-2 buffer gas is irradiat ed with ArF 1930-angstrom laser light. We present experimental evidenc e that the H- ion is responsible for this effect, through charge-neutr alizing collisions with Al+.
