Calculations energy of the (2s2 1S) Ground State and the (2p2 1D); (3d2 1G); (4f2 1I) Doubly Excited States of Helium isoelectronique sequence (Z ? 20) via the Modified Atomic Orbital Theory

We reported in this presentation the ground-state of (2s2 1S) and total energy of the (2p2 1D); (3d2 1G); (4f2 1I) Doubly Excited States of Helium isoelectronique sequence (Z ? 20), Calculations are performed using the Modified Atomic Orbital Theory (MAOT) [1-2] in the framework of a variational procedure [3] , the purpose of this study required a mathematical development of the hamiltonian appliedto Slater-type wave functioncombiningwithHylleraas-type wave function, Thestudy leads to analytical expressions whichare carried out under special MAXIMA computational program, this first proposed MAOT variational procedure, leads to accurate results in good agreement as well as with available other theoretical results than experimental data.
