One-electron processes in atomic physics

Abstract

In this work we have developed a Fortran 77 subroutine package to solve numerically the radial Schrödinger equation. We have also defined an adjustable radial grid with specific characteristics that permit solving the radial Schrödinger equation. The numerical method implemented is the Hamming predictor-corrector method that is started by expanding the solution at the first four point as a power series. Furthermore, using that package, we have computed the mean-life for spontaneous emissions between bound energy levels using a Coulomb potential with and without screening
