Dielectronic recombination calculations for neon and sodium-like selenium

The dielectronic satellite spectra of sodiumlike selenium (Se XXIV) are reported, and the analysis is extended with theoretical calculations of recombination rate coefficients for fluorinelike Se XXVI to form neonlike Se XXV and Se XXV to form Se XXIV. The required atomic parameters, line wavelengths and oscillator strengths, are calculated with the SUPERSTRUCTURE program in which 15 configurations are included. For the dielectronic recombination rate coefficients, all the theoretical formulas available in the literature are used.
