DIELECTRONIC RECOMBINATION OF LI-LIKE NEON AND ARGON

We have measured dielectronic recombination rates and energies for δn=0 transitions of Ne7+ and Ar15+ beams stored in CRYRING. The energy resolution was in the order of 10−2 eV FWHM; the absolute accuracy in the position of the resonances is in the same order. The energy positions of the dielectronic recombination resonances are compared to theoretical calculations of the fine-structure splittings.
