Abstract.

The energies of the levels belonging to a Rydberg series 1snp 1,3P in a two electron atom have been determined by means of the quantum defect theory for a two-electron atom with nuclear charge Z considered as a parameter. Comparison with configuration interaction calculations suggests that the analytic quantum defect expression for the energy levels may be in fact asymptotically exact as \(Z \to 1\), providing an analytic description of the disappearance of the Rydberg states with L > 0 when Z approaches the value of 1.
