Abstract

Self-consistent local-spin-density total-energy calculations for Cr2 and Mo2 yield g1+ ground states with dissociation energies and equilibrium bond lengths in excellent agreement with experiment-in marked contrast with the results of a generalized-valence-bond-van der Waals approach, which used 26 512 determinants, and previous local-density efforts. The present results indicate the reliability of local spin-density theory for very inhomogenous systems, when sufficient variational (and symmetry) freedom is included.
