Abstract
In this paper, we have declined the formalism of the method of the Modified Atomic Orbital Theory (MAOT) applied to the calculations of energies of doubly excited states 2 snp , 3 snp , and 4 snp Helium-like systems. Then we also applied the variational procedure of the Modified Atomic Orbital Theory to the computations of total energies, excitation energies of doubly-excited states 2 snp , 3 snp , 4 snp types of Helium-like systems. The results obtained in this work are in good agreement with the experimental and theoretical values available.
