Nature of problem:
The study of the collisional excitation of atoms by charged projectiles involves interaction matrix elements. These can be reduced to a sum of radial integrals involving hydrogenic wave functions, multiplied by functions of R. The integrals are calculated analytically to yield power series in R.
For large principal quantum numbers certain dimensions need to be increased.
