摘要
We present a detailed description of a procedure for the numerical evaluation of the first-order self-energy correction for an arbitrary excited state. An efficient schema of the numerical treatment of the many-potential part of the Dirac-Coulomb Green function improves the speed of the computation considerably. This feature is extremely important for higher-order self-energy calculations. We apply this method to the evaluation of the self-energy correction for the excited states with \kappa\less than or equal to 5 and n less than or equal to 5 for some high-Z ions.
