Abstract: A set of practical parametes on hydrogenic ions is given for electron-impact excitation cross sections and rate coefficients with transitions nl→n'l',n1,2,...,7, n'=2, 3,..., 8. Application ranges are 3≤ Z ≤74;x≥2 for n'≤5;x≥20 for n'≥5. The errors are generally about 30%.

Key words: H-like hydrogenic ions, electron-impact excitation cross sections
