Low energy electron-ion recombination experiments at CRYRING

Results from recent experiments at the heavy-ion synchrotron storage ring CRYRING are described. These experiments include radiative recombination of deuterons using several separate techniques to investigate specific n-level capture, and dielectronic recombination of He+ and Ar13+. New methods applied to the argon dielectronic recombination experiment provided an energy resolution better than 30 meV FWHM and a determination of the peak positions to ±30 meV.
