Variation of satellite intensity factors with n for 1${\mathit{s}}^2$εl →1s2pnl→1${\mathit{s}}^2$nl dielectronic-recombination processes in heliumlike ions

Satellite intensity factors ${\mathit{F}}_2^{\mathrm{*}}$(s-f) have been calculated for the 1${\mathit{s}}^2$εl→1s2pnl→1${\mathit{s}}^2$nl dielectronic-recombination processes of heliumlike Ne, Si, Ar, Ti, Cr, and Ni. The relevant atomic parameters have been calculated explicitly for all intermediate resonance states ‖s〉=‖1s2pnlSLJ〉 with n=2–8 and l=0–6 in the intermediate-coupling scheme. The 1/${\mathit{n}}^3$ scaling, which has often been used in extrapolating ${\mathit{F}}_2^{\mathrm{*}}$(s-f) for n≥4, is tested against these values of ${\mathit{F}}_2^{\mathrm{*}}$(s-f).
