Title of program: HYDROGENIC INTERACTION INTEGRAL Catalogue Id: ABWA_v1_0 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.
