摘要：

Calculation of the energy levels of atoms and ions with 2 <= Z <= 15 are carried out in this paper using a Hyllerass approximation. The method used is one of Screen Constant by Nuclear Charge Unit to calculate the total energy of two-electron atomic systems in ground and different doubly excited states. Employing a new wave function including correlation, we were able to calculate excited states (nl)(2) ( n <= 4). The Comparison of these results with the ones of other methods shows a good agreement.
