Variation of dielectronic satellite intensity factors with n for 1sεl → 2l'nl'' → 1snl'' dielectronic-recombination processes in selected hydrogen-like ions

Satellite intensity factors F2*(s→∫) of hydrogen-like silicon, calcium, titanium, and iron ions have been calculated for 1sεl→2l'nl'' → 1snl'' dielectronic-recombination processes. The relevant atomic parameters have been calculated explicitly for all intermediate resonance states up to n=8. Calculations have been performed in the intermediate coupling scheme using ab initio configuration interaction structures and wavefunctions computed using the Hartree-Fock atomic model. The 1/n3 scaling, which has often been used in extrapolating the F2*(s→∫)functions for n≥4, is tested against these explicitly calculated values. We find that the 1/n3 scaling can yield erroneous results for individual satellite lines. The satellite intensity factors summed over all states of each n, however, are in good agreement with the 1/n3 scaling as n approaches 8. (author)
