Energy Positions of the 1,3De Rydberg Series of the He-Like Ions Up to the N = 9 Threshold

The ( ) 1,3 , A n N KT De doubly excited states of helium-like ions are investigated using a combination of the no-linear parameters of Hylleraas and the ?-parameters of screening constant by unit nuclear charge. Calculations are performed for total energies of low-lying doubly excited states (N = 2 - 9) in He-like ions up to Z = 10. The results obtained from the novel method are in good agreement with the available theoretical calculations and experimental observations.
