Spline-Galerkin methods applied to Rydberg series between the 4s 2S and 3d 2D limits of calcium

Summary, in English

The recently introduced nonvariational spline-Galerkin method [T. Brage and C. Froese Fischer, Phys. Scr. 49, 651 (1994)] for Rydberg series is applied to the J = 0, 1, 2, and 3 even states between the two first limits in neutral calcium. Energies for 3dnl levels up to n = 15-20 are reported and the position of different perturbers belonging to the 4 p2 and 4p 5p configurations are investigated. The 4p 5p P-1(1) level is predicted to have an excitation energy of about 61 200 cm-1 and the 4p 5p 3D level is predicted at about 61 600-62 000 cm-1, while the 4p 5p 3P is just at the 3d2D limit.
