Abstract

We have investigated the doubly excited nonautoionizing states of heliumlike two electron ions from Li+ through Mg10+ using the exponential correlated exponential wave functions in the framework of the Ritz variational method. The metastable bound-excited 2pnf 1,3Fe(4 ≤ n ≤ 7) and 2png 1,3Go (5 ≤ n ≤ 8) states energies of heliumlike two-electron ions are reported along with the 2png 1,3 Go (5 ≤ n ≤ 9) state energy eigenvalues of helium atom. Our upper-bound results for the 2pnf 1,3Fe and 2png 1,3Go states energies of Li+, Be2+, B3+ are the lowest values up to this date. The doubly excited nonautoionizing F and G states energy eigenvalues for heliumlike two-electron systems from C4+ through Mg10+ are reported for the first time in the literature.
