摘要：
The ground state of NaV2O5 was investigated in terms of the Hartree approximation for both on-site and intersite Coulomb interactions. A zigzag-type of charge disproportionation (i.e. charge ordering) along the ladders of V ions is found to be the most stable, instead of the one-dimensional arrays of V4+ ions so far presumed.
