摘要
Feynman's path integral formulation of quantum mechanics, supplemented by an approximate pseudopotential to account for exchange, is used to determine the vertical ionization potentials of Na3-Na6. Results are in good agreement with both the trends and the quantitative results of earlier work. We observe that the amount of discretization necessary to obtain converged energies is greater than that needed to obtain qualitatively correct information regarding the nature of the correlated wave function.
