【 摘 要 】

Calculation of the electronic density and potential distribution in the field of a homogeneously charged core of a large radius are reviewed. The Hartree-Fock self-consistent field method and the density-functional method are applied for the problem. These methods are compared with simple model where not interacting electrons are in spherical potential well with infinite border. The applicability of model with infinite potential well is discussed.
