D/sup -/ negative-ion equilibrium fractions of deuterium in collisions with Mg, Ca, Sr, and Ba alkaline-earth-metal vapors have been measured over the energy range 1.25--100 keV. For Ca, Sr, and Ba targets, the yield of D/sup -/ ions is almost completely independent of the identity of the target over the energy range 4--35 keV. At low energies, an abrupt increase in D/sup -/ production is observed for targets of Ca, Sr, and Ba but not Mg, and occurs at approximately the same energy, 4 keV, in all three cases. Possible mechanisms responsible for the structure in D/sup -/ production are discussed.
