The Inter-Shell Doubly Excited 1,3S^e, 1,3P^o, 1,3D^e, 1,3F^o, and 1,3G^e States Energies Calculations of Helium-Like Ions Using Special Forms of Hylleraas-Type Wave Functions

並列摘要


The inter-shell singlet and triplet doubly excited states energies of helium-like ions have been calculated by using special forms of Hylleraas-type wave functions. The calculations of these inter-shell nln'l and nln'l' (with n ≤ 3, n' ≤ 4 and l = l' or l ≠ l') singlet and triplet doubly excited states energies of helium-like ions have been carried out in the framework of the variational method using configuration interaction basis states with a real Hamiltonian. Comparisons are made with the other theoretical calculations and some experimental data.
