Radiative recombination of C$^{6+}$ ions with free electrons was studied 
at the storage ring TSR through a systematic variation of relevant parameters 
such as the magnetic field and the electron density in the electron 
cooler. The electron beam was characterized independently by observation of a
narrow dielectronic recombination resonance in F$^{6+}$. A distinct 
dependence of the rate anomaly at zero energy on the magnetic field was
observed.
