We report calculations of the cross-sections for electron impact detachment of the diatomic anions B2-, O2-, BO-, and CN- using the DM formalism. The calculations use 'ionic' weighting factors to adequately represent the ionic character of the target and in each case a Mulliken population analysis of the anion and the neutral molecule was carried out in an effort to localize the 'extra' electron in the anion compared to the neutral molecule. When compared with available experimental data, the calculated DM cross-sections were found to exceed the measured data by factors ranging from 1.6 to 5.5.
