| dc.description.abstract | Electron-electron correlation forms the basis of difficulties encountered in many-body physics.
Accurate treatment of the correlation problem is likely to unravel some nice physical properties of
matter embedded in the correlation. In an effort to tackle the many-body problem, an empirically
determined symmetry-dependent partition fraction for the electron-electron interaction energy between two interacting states of helium atom is suggested in this study. Using the partition fraction
and the lowest-order approximation of the multipole series expansion of the electron-electron interaction, a simple parameter-free pseudopotential for a two-electron system is derived. The groundstate, singly and doubly excited state non-relativistic energies generated by the pseudopotential are
in reasonable agreement with literature values. | en_US |
