The 1snsS Rydberg series in a two-electron system with the charge of the nucleus, Z'1 is treated by means of the quantum-defect theory. Comparison with configuration interaction calculations suggests that the quantum-defect expression for the energy levels becomes asymptotically exact as Z→1. This provides an analytic description of the disappearance of the… CONTINUE READING
