Spline-Galerkin methods for Rydberg series, including Breit-Pauli effects

Summary, in English

We discuss the recently introduced spline-Galerkin method for Rydberg series of atomic systems, and extend it to Breit-Pauli configuration interaction calculations. Special emphasis is put on the efficient evaluation of the different radial integrals appearing in these calculations. An application to the 1De series of beryllium illustrates the potential of the method in the non-relativistic case. A Breit-Pauli calculation for the J = 1 odd Rydberg series above the lowest 4s 2S limit of calcium is reported. The resulting energies agree very well with recent experiments.
