An ab initio calculation of the cross-sections of dissociative recombination (DR)in Hf, HID" and 07 has been made using the projection operator technique.A single-configuration molecular orbital wavefunction has been used for themolecular resonance state, although the applicability of such a simple wavefunc-tion has not been fully tested. The decay width has been calculated in the "local"approximation. Comparison with experiment shows that for Hf the calculatedresults can fully account for the total DR cross-section in the low and intermediateenergy regions, and that the local approximation is sufficiently accurate to accountfor the undulatory structure in the energy dependence of the DR cross-section.A similar structure is also obtained for 07, although here the agreement withexperiment is less marked. For HD" no particular heteronuclearity effect isobserved.
