Algebraic tools for dealing with the atomic shell model. I. Wavefunctions and integrals for hydrogen-like ions

In order to suppor... Title of program: DIRAC Catalogue Id: ADUQ_v1_0 Nature of problem Analytical solutions of the hydrogen atom are widely used in very different fields of physics [2,3]. Despite the rather simple structure of the hydrogen-like ions, however, the underlying 'mathematics' is not always that easy to deal with.

Apart from the well-known level structure of these ions as obtained from either the Schrodinger or Dirac equation, namely, a great deal of other properties are often needed. These properties are related to the interaction of bound electron(s) with external par ...
