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.
