The cross sections for electron detachment from negative carbon ions in Mg, N/sub 2/, and CO and from negative oxygen ions in N/sub 2/ and CO are measured over the energy range 20--150 keV for the negative ions. The cross sections for electron detachment from negative carbon ions in the ground and excited states are distinguished on the basis of the decay of weakly bound states of the atomic particles in strong electric fields through the process C/sup -/+Mg..-->..C. The cross sections for electron detachment from the C/sup -/ ions in the bound and excited states behave in different ways as functions of the velocity. The difference is interpreted as evidence for two different detachment mechanisms.
