Keywords: Atomic physics, Hydrogenic Wave function, Radial integral, Interaction, Matrix element, Power series. | ||

Classification: 2.7. | ||

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. | ||

Restrictions:For large principal quantum numbers certain dimensions need to be increased. | ||
