| dc.description.abstract | Electron-electron correlation forms the basis of difficulties encountered in many-body
problems. Accurate treatment of the correlation problem is likely to unravel some nice physical
properties of matter embedded in this correlation. In an effort to tackle this many-body problem,
a classical partition function for the electron-electron correlation between two interacting states is
proposed in this study. Using this partition function, a model potential for a two-electron system is
derived. The model potential can accurately reproduce the singlet states of a singly excited neutral
helium atom with one of its electrons frozen in the 1s orbital. | en_US |
