Abstract

Analytical approximations to the solution of the Thomas-Fermi and Thomas-Fermi-Dirac-Weizsäcker equation for neutral systems are presented. The authors demonstrate in detail the quality of the solutions for one-center boundary conditions and provide an extension for two-center systems. Finally, the construction of effective single-particle potentials for diatomic systems based on the solutions obtained is discussed.
